Crafting a Legendary or Epic Hearthstone card is a big decision. Our tier list will help you decide what to craft so you won't regret it later.

So when you’re just starting out, Hearthstone is certainly a daunting game to jump into. But like other players you’ve likely already decided that you want to climb past Rank 20. As a new player with eyes on legend, it is very easy to watch a stream and fall in love with a deck. However, you can dump a ton of money into building that deck only to find out that you really don’t care for its playstyle. This is an easy trap to fall into. It’s a great way to burn your entire budget with very little to show for it.

For new players on a budget, one of the most important things to know is how to manage the two resources found in the world of Hearthstone, gold, and dust. There is no right or wrong way to use these, but it is extremely important to spend them with a goal in mind when you’re first learning the game.

I believe that the best way to budget your resources, learn about the game, and build somewhat competitive decks is to craft only the most versatile cards in top tier decks you see in decklists. These are the legendaries and epics that can also be used in other decks. Try not to put all your eggs in one basket and avoid crafting expensive niche cards. Instead, stick to budget replacements.

Some legendaries are played in decks only because they are marginally better than a rare or common alternative. You can get by without these, at least until you try the deck. Still, some legendaries are irreplaceable. This guide will give some examples of how to think about crafting decisions and I’ll rank legendaries in accordance with how useful I think they are to the new player.

Keep in mind that this guide isn’t meant to be followed to the letter. If you love Paladin, go ahead, by all means, craft Tirion Fordring and Ragnaros, Lightlord. They have a place in almost every Paladin variant. However, if you’re not completely 100% sold on Uther then stick to the guide and get yourself some Classic and neutral legendaries first. Being a “one-trick” isn’t as much of a thing in Hearthstone as it is in other games. It’s almost unheard of for a high-level player to be 100% devoted to a single class, so try to diversify.

Deckbuilding as a New Player

When first starting to learn Hearthstone on any kind of budget, it’s best to focus on collection building. I can’t stress the importance of “try before you buy” in Hearthstone. If you’re on a budget do not give into the temptation of picking a deck to build and immediately crafting all of the expensive cards for it. Sure, this will give you a sense of instant gratification, especially if you’re winning with the powerful deck at your rank. The people you were once losing to will likely fold under the power of your newly crafted cards. But that feeling won’t last. Inevitably, you will eventually plateau and stagnate if you don’t have experience under your belt. Good cards can only carry you so far.

There will come a point where the more powerful deck no longer can carry you up ranks. Building and playing other decks is a good way to get experience in a variety of situations, but without a solid collection to stand on, it can become very frustrating to be a mid-level Hearthstone player on a budget.

When crafting and dusting cards it’s important to keep in mind the principle of versatility. For a new player, the best cards are the ones with a great deal of usability in several decks. For that reason, the tier list below prioritizes neutral legendaries.

For example, Kalimos, Primal Lord gives elemental decks a lot of their power. You shouldn’t expect an elemental deck to work very well without its flagship elemental. However, Kalimos is a card with an extremely narrow range of usage. It’s playable in dedicated elemental decks only. Many cards from Journey to Un’Goro, especially the Quests, fall into this category. These cards basically force the player to build decks around them, as opposed to most cards from the Classic set which fit more easily into existing decks. Since Quests require the player to build a deck around a single card, they’re not ideal for new players. They have a very narrow use and aren’t nearly as versatile as legendary minions.

It’s important to consider the card rotation as well, which is scheduled to happen every year; the next time being whenever the first expansion of 2018 drops. At this point, all the current standard sets will presumably rotate out except for the 2017 sets - Journey to Un’Goro, Knights of the Frozen Throne and the last expansion of this year (which we still don't know). When you’re trying to build a collection, focus on collecting legendary cards from the Classic set and the cards that aren't going to rotate next year (so right now, cards from 2017).

Legendary Crafting Tier List

It’s important to stress that this is a crafting tier list for new players, not a power ranking. For example, Ysera is a card that is almost never played in standard decks. The card is pretty high up on the tier list relative to its strength in Standard. This is because it’s such a great high-cost card to cap off a budget deck and will probably see play down the road. Conversely, cards like Wickerflame Burnbristle and Shaku, the Collector are quite far down on the tier list because they are soon to rotate and only marginally improve the few decks they see play in, despite seeing play more frequently than the example of Ysera above.

Cards are rated on the following principles.

  • Does this card improve many different decks?
  • Is the card likely to see play in the future?
  • Will this card be removed from standard soon?
  • Is the card useful across classes?
  • Does the card require you to play other cards alongside it?

 

You might notice that C'Thun (uncraftable) and legendaries from the One Night in Karazhan adventure are excluded from this list. This is because these cards don’t compete for dust like expansion legendaries do. If you’re putting real money into Hearthstone, consider just shelling out for Karazhan. It’s extremely slow to purchase using gold. Speed up the process for a price of $19.99, which translates to 15 packs (which at a minimum would likely net you around 1,500 dust). Karazhan gives nearly 3,000 dust value and many exclusive staple cards including Swashburglar, Maelstrom Portal, and Babbling Book.These improve nearly any deck they’re put in. In fact, every class benefits heavily from ONiK, especially when you’re first starting out. Spending money to get Karazhan saves a ton of time grinding for gold and gives great value in dust, considering the cost of packs.

Important: Cards tagged with an asterisk (*) are due to rotate out from Standard with the first expansion of 2018. Some of those cards are great crafts right now, but if your aim is to have a long-term playable collection, you should put a lower priority on them.

Legendary Tier List

S Tier

These are the best, most versatile Legendary cards in Hearthstone. These are staple cards in every collection. They improve the power level of several strong decks and will likely continue to do so in the future. They're also great crafting options for the players on budget, because they fit into so many lists.

Card Name Set Class Commentary
 Bloodmage Thalnos   Classic   Neutral  No longer the staple it once was, but it can find its way into just about any deck. Very versatile and bound to be great in the future. 
 Patches the Pirate (*)  Gadgetzan  Neutral  Auto-include into pretty much any Aggro deck. If you're mainly playing Aggro, it's your highest priority craft.
 The Lich King   KFT  Neutral Powerful late game card, generally a better version of Ysera. Pretty common in competitive decks, but more importantly it's one of the best crafts for new players, because it can improve lots of budget decks.

A Tier

These cards are all likely to see use in the future. These are either extremely useful in most budget decks or great in current high-end archetypes. They will likely see play in several future decks and are unlikely to be pushed out of the meta by more powerful cards.

Card Name Set Class  Commentary
 Aya Blackpaw (*)  Gadgetzan  Druid, Shaman, Rogue Auto-include into every Jade decks. Even though the uses are pretty narrow, Jade lists are great for new players (cheap and easy to learn) and Jade Druid is a very powerful deck right now.
 Tirion Fordring   Classic  Paladin Played in every Paladin deck. Incredibly versatile Classic card for the entire Paladin Class. Contender for the best minion in Standard. Anyone who plays Paladin may as well craft it. 
 Alexstrasza  Classic  Neutral There was no meta where Alexstrasza has seen no play, that's why it's generally considered a safe craft. Mostly played in Mage, but you can find some uses for it in many slower decks.
 Leeroy Jenkins  Classic  Neutral Similarly to Alexstrasza, Leeroy is one of the safest crafts. It can be played as finisher in multiple Aggro decks and it's never completely out of the meta.
 Fandral Staghelm (*)  Old Gods  Druid Staple Druid Legendary, used in multiple deck lists. Since "Choose One" cards are quite common, Fandral can snowball the game by itself if left unanswered.
 Sunkeeper Tarim  Un'Goro  Paladin Tarim is very close to Tirion Fordring in terms of the power level, but unlike Tirion, it will eventually rotate out. Still a great craft if you want to play Paladin - it fits just about any build.
 Malfurion the Pestilent  KFT  Druid Best Hero card to craft right now - Druid is the best class, and Malfurion the Pestilent improves any slower Druid deck. It provides an okay immediate impact and a solid upgrade on the Hero Power. 
 Elise the Trailblazer  Un'Goro  Neutral  Best in Priest, but you can run her in any Control-oriented build. Definitely will improve slower budget decks as a solid 5-drop.
 Edwin VanCleef  Classic  Rogue The only Rogue staple Legendary, used in many lists ever since Classic, also a great choice in budget decks.
 Archmage Antonidas  Classic  Mage Another Classic staple - Antondias is used as a finisher in multiple Mage decks, most often in Freeze variant. Right now played in Tempo Mage and Quest (Exodia) Mage.

B Tier

Generally great cards and likely to see play in the future. Having these cards improve most budget decks. However, they either are only played in a few specific competitive decks or are only conditionally playable if the player owns other cards (the Deathrattle synergy with N’Zoth for example).

Card Name Set Class Commentary
 Shadowreaper Anduin  KFT  Priest  Best to play in the Highlander Priest list with Raza the Chained, but you can run it in any slower Priest deck as another board clear with upgraded Hero Power.
 Lyra the Sunshard  Un'Goro  Priest  The card got a little weaker in Frozen Throne, because a lot of expensive spells were added and it's harder to chain them. Still a good value generator in Priest decks.
 Wickerflame Burnbristle (*)  Old Gods   Paladin  Great anti-Aggro card. It's a good addition into just about any Paladin list, but not as necessary as Tirion or Tarim, and it rotates out sooner.
 Finja, the Flying Star (*)  Gadgetzan  Neutral  If you run Murloc deck, or at least Murloc package (Murloc Warleaders + Bluegill Warriors, like some Aggro Druids), you will most likely want to play Finja too. 
 The Black Knight  Classic   Neutral One of the best tech cards in the current meta. Likely to see play any time a heavy Taunt meta is seen. And it's Classic, so it won't rotate out. 
 N'Zoth, the Corruptor (*)  Old Gods  Neutral The best neutral legendary in WotOG but completely dependant on the quality of Deathrattle minions you own. Powerful, but needs to be built around.
 Ysera  Classic  Neutral Outshined by The Lich King in most of the decks. However, it's still a solid card to run in something like Big Priest or a good addition to slower budget decks (especially Dragon-oriented).

C Tier

These cards are about average. As a new player, you probably wouldn’t want to craft one, but you generally don't mind opening one. Most of these cards have niche use and will probably see play in the future. Not as useful to craft because their use tends to be narrow compared to the broader impact enjoyed by the cards above.

Card Name Set Class  Commentary
 Bloodreaver Gul'dan  KFT  Warlock Possibly the best Hero card from Frozen Throne, staple in slower Warlock decks, but the class isn't in a great shape right now. Will likely see play in the future too.
 Cairne Bloodhoof  Classic  Neutral Solid, high value card to put as a 6-drop into your budget decks. Played in some Deathrattle decks, but mostly a new players card.
 Raza the Chained (*)  Gadgetzan   Priest  Necessary if you want to play Highlander Priest. It's a good and fun deck, but the card is so low, because it's useless outside of that one, specific deck.
 Thrall, Deathseer  KFT  Shaman Common card in the Evolve/Token Shaman decks. It's solid, but the decks built around it are still not optimized. Might see more play in the future.
 Pyros  Un'Goro   Mage Played by some Tempo Mage lists as a growing threat. Can also be played in Elemental Mage. Solid in a lot of budget Mage lists.
 Y'Shaarj, Rage Unbound (*)  Old Gods   Neutral Played in slower decks with big minions, especially alongside Barnes. Can be used in Big Priest or Ramp Druid. Okay budget late game choice.
 Grommash Hellscream  Classic   Warrior Right now only sometimes used as a finisher in Tempo Warrior, but it will improve any budget Warrior deck and will most likely see play in the future.
 Malygos  Classic   Neutral  A great high-cost body for classes that benefit from spell damage like Druid and Mage. Strong body, but needs a deck built around it to be effective.
 Yogg-Saron, Hope's End (*)  Old Gods  Neutral No longer a staple since it was nerfed, but it can still be played as a "panic button" in some classes like Druid or Mage. 
 Frost Lich Jaina  KFT  Mage While it's not common right now, since Control Mage isn't very powerful in the current meta, it will greatly improve most of the slower budget Mage decks.
 Prince Keleseth  KFT  Neutral Played in multiple decks, but they're all low tier or off-meta (e.g. Handbuff Paladin, Zoo Warlock). The effect is incredibly powerful, but you need to build your deck around it, which makes it less consistent.
 Sherazin, Corpse Flower  Un'Goro  Rogue First of the two 4-drop choices for Miracle Rogue. Better when you face a slower meta. Pretty low on the list, because Miracle Rogue is not considered a good deck for new players.
 Prince Valanar  KFT  Neutral Second of the two 4-drop choices for Miracle Rogue. Better when you face a faster meta. Pretty low on the list, because Miracle Rogue is not considered a good deck for new players.
 Open the Waygate  Un'Goro  Mage Played in a single deck - Quest (Exodia) Mage. The deck is effective in a slower meta, it's a low tier deck right now and it will probably see some play in the future. The deck can be fun, but it's very hard to play, so not recommended for new players.
 Kazakus (*)  Gadgetzan  Mage, Priest, Warlock Staple in Highlander decks (decks that run only 1 copy of each card), however right now the only viable Highlander deck in standard is Priest and Raza gets a higher priority there. 
 Shaku, the Collector (*)  Gadgetzan  Rogue Rogue class is pretty low on good 3-drops and it's the reason why the card is sometimes seen. It's a good card if you play a lot of Rogue, but it's not necessary by any means.
 Ragnaros, Lightlord (*)  Old Gods  Paladin Great card to play in any slower Paladin deck. However, right now those slower Paladin decks aren't very common, as they were pushed by the faster, Murloc-oriented versions.
 Prophet Velen  Classic  Priest It has seen play every now and then, mostly in the combo variants. Right now semi-common in Highlander Priest as a combo finisher. 
 Bolvar, Fireblood  KFT   Paladin Played as a 5-drop option in some Murloc Paladin decks, but definitely not a necessary card. Solid in budget Paladin list. Maybe will see more play in the future.
 Baron Geddon  Classic  Neutral Historically, the card has seen most play in Control Warrior, but it got ditched when the deck has got other AoE tools (like Sleep with the Fishes). Right now used in Control Mage with a new Hero card. Will probably see some more play in the future.
 Uther of the Ebon Blade  KFT Paladin Paladin Hero, it fits the Control Paladin decks. Not very common right now, but it will most likely see play whenever the meta starts favoring them more.
 Deathwing  Classic  Neutral Never common in the meta, but it has seen play time and time again over the time. Used as a secondary win condition in faster decks, or "panic button" in slower ones.
 Lord Jaraxxus  Classic  Warlock It has seen play before in the Handlock and RenoLock archetypes. Right now mostly replaced by the Bloodreaver Gul'dan, but it has a high chance to see play in the future.
 Al'Akir the Windlord  Classic  Shaman While the card was never a staple in any deck, it was played in multiple Shaman variants since Classic - mostly as a finisher in Midrange (and Elemental) decks. Should improve budget Shaman decks.
 Twin Emperor Vek'lor (*)  Old Gods  Neutral Staple if you plan to play a C'Thun deck (e.g. C'Thun Druid or C'Thun Priest). But the C'Thun decks are generally only the budget options and they aren't played as the meta decks.

D Tier

These are the last viable Legendaries that you might encounter in the Knights of the Frozen Throne meta. They are generally on the edge between being playable and unplayable. These are uncommon to see on the ladder, but situationally useful in competitive decks. Some of them are staples in the low-tier meta decks, or even off-meta decks. You definitely don't want to craft them unless you're sure that you want to play that one, specific deck they're played in. Not recommended for new players with low Dust budget. 

Card Name Set Class Commentary
 Scourgelord Garrosh  KFT  Warrior Played only in a single, low-tier deck - Tempo Warrior (including the Dead Man's Hand variants). Good only if you plan to play that deck, but not recommended for the new players.
 Kalimos, Primal Lord  Un'Goro  Shaman The card fits only a single, low-tier deck - Elemental Shaman. It's a great card in that deck, but it's not a great craft.
 Captain Greenskin  Classic   Neutral A tech card in Pirate Warrior, not played outside of it. Might be okay budget option if you run a Pirate, or other weapon-heavy deck.
 Harrison Jones  Classic   Neutral  Best weapon destruction tech in the Control meta. However, it has been mostly pushed out by the more tempo-oriented (and cheaper) options like Acidic Swamp Ooze or Gluttonous Ooze.
 Arfus  KFT  Neutral Good value card, sees play in some Deathrattle lists, but it's too slow for most of the metas.
 Kun the Forgotten King (*)  Gadgetzan   Druid Sees some play in the Jade and Ramp Druid decks, but it's only a tech, it's definitely not necessary to play those lists.
 Deathstalker Rexxar  KFT  Hunter This Hero card is on a verge of playability - good option in slower Hunter lists, but the decks built around it just aren't powerful enough, because Hunter wants to be more aggressive.
 White Eyes (*)  Gadgetzan   Shaman  Good card in Deathrattle/Control Shaman, but mostly played in the Wild, because the archetype is more powerful there. 
 Fire Plume's Heart  Un'Goro  Warrior Taunt Warrior was a solid deck back in Un'Goro, but it's very weak in the current Jade Druid-infested meta. It might come back into the meta, but it's a low tier deck right now.
 Cenarius  Classic   Druid Solid addition into budget Druid decks, but when it comes to the meta decks, it only sees niche play in Midrange Token decks. Not worth the crafting, but it might come handy sometimes.
 Hallazeal the Ascended (*)  Old Gods  Shaman Good in spell-heavy, Control Shaman deck. Can combo well with AoE cards like Lightning Storm or Volcano (even though it can die, it's a nice burst healing). However, those decks aren't popular or good right now.
 Deathwing, Dragonlord (*)  Old Gods  Neutral Sees niche play in Ramp Druid. It's a big body that can swing the tempo heavily when it dies. Can be used as a high cost Dragon in the budget Dragon decks.
 King Mukla  Classic  Neutral From time to time, it sees some play in Aggro decks, because the 5/5 body for 3 is a really solid tempo move. However, mostly out of the meta right now.
 Auctionmaster Beardo  Gadgetzan  Neutral Used in the OTK Paladin alongside Uther of the Ebon Blade, but it's not a good deck. Can be put into budget lists as a 3 mana 3/4 with some late game potential.
 

E Tier

If you haven't found the card you want to craft above, it means that it belongs to the last Tier - E Tier. Those cards aren't worth crafting. They aren't really good choices in the budget decks, they are overshadowed by better cards and they aren't generally useful right now. It doesn't mean that they're completely useless - sometimes a E Tier card gets support in a new expansion and jumps even as high as Tier A or B. Other times a new deck emerges that runs it as a tech card and it might become a D Tier card. Some of those cards might also be used in off-meta, "fun" decks, so if you like one in particular, there is nothing wrong with crafting it. You just need to understand that it's not and it's very likely to never be a competitive card.
 

Epic Tier List

Note: If you want only a single copy of a given epic, I'll note that in the "Commentary". If nothing is there, it means that you most likely want to have two copies of the card.

S Tier

These are the best, most versatile epic cards in Hearthstone. These are staple cards in every collection. They improve the power level of several strong decks and will likely continue to do so in the future. They're also great crafting options for the players on budget, because they fit into so many lists.

Card Name Set Class Commentary
 Doomsayer  Classic   Neutral  The most staple Epic card, one of the best anti-Aggro option in the whole game. 
 Primordial Drake  Un'Goro  Neutral  Big body with Taunt and AoE damage is a great mix that got into many different meta decks. 

A Tier

These cards are all likely to see use in the future. These are either extremely useful in most budget decks or great in current high-end archetypes. They will likely see play in several future decks and are unlikely to be pushed out of the meta by more powerful cards.

Card Name Set Class Commentary
 Ice Block  Classic  Mage One of the most staple Mage cards, used by every single slower Mage deck since Classic. Necessary if you want to play decks like Burn Mage, Freeze Mage or Quest Mage.
 Murloc Warleader  Classic  Neutral Auto-include into every Murloc deck that ever was and probably ever be - the card snowballs the Murloc boards like crazy. 
 Ultimate Infestation  KFT  Druid Used by some of the best meta decks right now, including Jade Druid. One of the most powerful cards in the whole expansion.
 Gentle Megasaur  Un'Goro  Neutral Another Murloc decks staple - powerhouse card on any board with Murlocs. The card's power level is very similar to the Warleader, but it's a bit lower, because it will eventually rotate out.
 Preparation  Classic  Rogue Rogue staple, used by many different decks, but most successfully by the Miracle Rogue. If you want to play the class seriously, you do want to have this card.
 Brawl  Classic  Warrior Even though the card doesn't see a lot of play right now, historically it's been used by every slower Warrior deck. One of the best AoE clears in the game. 
 Hungry Crab  Classic  Neutral After listing two Murloc staples above, here is an anti-Murloc staple. Used very commonly in a Murloc-heavy meta, the card will be handy as long as people play Murloc decks.
 Southsea Captain  Classic  Neutral It's like a Warleader, but for the Pirates. It's a bit weaker, but it's still auto-include into most of the Pirate builds. 
 Dragonfire Potion (*)  Gadgetzan  Priest If you want to play a slower Priest deck (not necessarily Dragon), you simply need this card. The only powerful AoE clear option available for the class right now.
 Shadow Visions  Un'Goro  Priest While a little less important than Dragonfire, it's a staple in literally every single Priest deck - the ability to tutor a specific card from your deck is very strong. 
 Primordial Glyph  Un'Goro  Mage Very flexible card that can fetch any spell - this card will get you out of trouble often than you think. Played in every single Mage deck.

B Tier

Generally great cards and likely to see play in the future. Having these cards improve most budget decks. However, they either are only played in a few specific competitive decks or are only conditionally playable if the player owns other cards (the Deathrattle synergy with N’Zoth for example).

Card Name Set Class Commentary
 Living Mana  Un'Goro  Druid While it's played in only a single archetype - Token Druid - it's one of the most important cards in the deck. While you can replace it, the deck's ability to refill the board will suffer greatly.
 Bittertide Hydra  Un'Goro  Neutral Hydra is like a Fel Reaver of this Standard rotation, can be played in some of the top tier meta decks like Aggro Druid or Pirate Warrior. However, it's not Tier A, because it can be quite easily replaced.
 Vilefin Inquisitor (*)  Old Gods  Paladin Another very powerful card that's played only in a specific archetype - in Murloc-oriented Paladin decks (so Aggro Murloc and Midrange Murloc). Turning the Hero Power tokens into Murlocs improves the cards like Warleader or Megasaur greatly.
 Twisting Nether  Classic   Warlock Staple Warlock AoE removal, used in most of the slower decks. While it costs a lot, it completely removes everything from the board, making it one of the strongest late game board clears. It's in B Tier, because Warlock is not that great right now.
 Shield Slam  Classic  Warrior Alongside the Execute, it's the second staple Control Warrior single target removal. Even though the deck is not very popular right now, the card is so powerful that it will definitely get back into the meta eventually.
 Skulking Geist  KFT  Neutral 1 copy. New tech card, mostly used against the Jade Druid. While it's a good craft right now, it only fits the slower decks (that can actually beat the Jade Druid when they can't go infinite). The card's power would also go down heavily if Jade Druid left the meta for some reason (e.g. nerfs). 
 Dirty Rat (*)  Gadgetzan  Neutral It used to be a very common tech card in the Gadgetzan and Un'Goro meta, but its popularity has gone down recently. It's stll a good tech, especially against combo decks (like Quest Mage).
 Vilespine Slayer  Un'Goro   Rogue A very powerful tempo card, Assassinate with a 3/4 body as long as you can combo it. Played in a lot of Rogue decks like Miracle or Tempo Rogue.
 Burgly Bully (*)  Gadgetzan  Neutral It's a pretty common tech in any deck that takes advantage of extra coins. It used to see some play in Rogue, but more recently it's been played in Tempo Mage (to combo with Archmage Antonidas) and OTK Paladin.
 Curious Glimmerroot  Un'Goro  Priest A new staple Priest card that pretty much replaced the Thoughtsteal in the top tier decks. Not only it gives the player some value, but also provides a 3/3 body on the board. Good mix of tempo and value.
 Sleep with the Fishes (*)  Gadgetzan  Warrior One of the best ways to deal with mid-sized boards, as long as you have a Whirlwind effect to combo it with. Lower than the Brawl, because it will rotate out relatively soon.
 Cabal Shadow Priest  Classic  Priest Classic Priest card, great in any meta with valuable 2 or less Attack minions. Can be combo'd with Pint-Size Potion to steal up to 5 Attack minions. Solid in budget Priest builds.
 Gluttonous Ooze  Un'Goro  Neutral 1 copy. Tech card, weapon removal. It's probably the best one currently available, but it's pretty low on the priority list, because it can be easily replaced by the Basic Acidic Swamp Ooze.

C Tier

These cards are about average. As a new player, you probably wouldn’t want to craft one, but you generally don't mind opening one. Most of these cards have niche use and will probably see play in the future. Not as useful to craft because their use tends to be narrow compared to the broader impact enjoyed by the cards above.

Card Name Set Class  Commentary
 Faceless Shambler (*)  Old Gods  Neutral Played in decks that run cheap, big bodies like Handlock (Mountain Giant) or Silence Priest (Humongous Razorleaf). Not common in the current meta.
 Faceless Manipulator  Classic  Neutral 1 copy. It was used like Faceless Shambler before it was released, in Handlock, to copy big minions. It's more expensive, but also more flexible - can copy opponent's minions. Might be used in some combo decks.
 Pyroblast  Classic  Mage Played as a finisher in some Mage builds. The card was common in different metas, but was never really necessary for those Mage decks to function.
 Cabalist's Tome (*)  Old Gods  Mage Used in Control decks as a value generator + in Quest Mage as a way to get spells from outside of your deck. Not very common, but can be useful.
 Obsidian Statue  KFT  Priest A solid Priest minion - Taunt, Lifesteal and strong Deathrattle is a nice combination. However, most of the Priest decks are faster now, so Statue is only used by the Big Priest as a revive target.
 Corpsetaker  KFT  Neutral Even though the card is Neutral, it could as well be Paladin's. The class can easily activate 3 out of 4 effects (Taunt, Divine Shield, Lifesteal) and for that reason it's used in some Midrange Paladin builds.
 Spirit Echo  Un'Goro  Shaman Card draw for Shaman, very strong card, but has niche uses, as the slower Shaman decks aren't very popular right now. Could be better in the future sets.
 Meteor  Un'Goro  Mage A very powerful Mage removal, used in Burn/Control decks as a single target removal with a slight AoE. The card is pretty low on the list, as it can be replaced quite easily (e.g. Polymorph, Flamestrike or Blizzard).
 Snake Trap  Classic  Hunter One of the most powerful Classic Hunter Secrets, played commonly in the Hunter builds that run Secrets/Secret synergies. While it's uncommon right now, it will certainly find home in the future and it will improve a budget Hunter deck.

D Tier

These are the last viable Epic that you might encounter in the Knights of the Frozen Throne meta. They are generally on the edge between being playable and unplayable. These are uncommon to see on the ladder, but situationally useful in competitive decks. Some of them are staples in the low-tier meta decks, or even off-meta decks. You definitely don't want to craft them unless you're sure that you want to play that one, specific deck they're played in. Not recommended for new players with low Dust budget. 

Card Name Set Class Commentary
 Mountain Giant  Classic  Neutral One of the Giants, this one is tied to the number of cards in your hand, thus played in the decks that hold a lot of cards, mostly Handlock. Not seeing a lot of play right now.
 Sea Giant  Classic  Neutral Yet another Giant, this time tied to the number of minions in play. Most commonly seen in flood decks like Zoo Warlock or Token Shaman variants. Not seeing a lot of play right now.
 Spellbender  Classic   Mage 1 copy. Solid Secret in a buff-heavy meta, e.g. against a lot of Paladins. However, rarely necessary, as it can be replaced by Counterspell quite easily.
 Rat Pack (*)  Gadgetzan  Hunter  Used to be a staple 3-drop in the Midrange Hunter decks, now it's less common ever since Bearshark was released. Still finds place in some of the decks, but it's not necessary.
 Ancient of War  Classic  Druid It was a staple Taunt minion in the slower Druid decks, now that the meta has shifted a bit and Silence / The Black Knight are much more common, it sees no play. Will probably come back in the future.
 Lay on Hands  Classic  Paladin 1 copy. Classic healing/hand refill played in the slower Midrange and Control Paladin builds. Those decks aren't common right now, so the card only sees niche play.
 Gorehowl  Classic  Warrior 1 copy. Used to be a staple Control Warrior card, but since the deck isn't common right now, the Gorehowl sees no play. It will probably be played in the future.
 Shadowcaster (*)  Old Gods  Rogue Generally used in some weird builds made around copying the cards, like C'Thun Rogue or Quest Rogue (post-nerf). Mostly off-meta card.
 Forbidden Healing (*)  Old Gods  Paladin 1 copy. Another healing option in Paladin, it was commonly seen in the Control Paladin lists, but now they're mostly gone.
 Blood Warriors (*)  Old Gods  Warrior Used in combo decks, mostly with Arcane Giants (you can play them for free in the late game, Whirlwind and get more copies which are also free). Mostly off-meta card.
 Dead Man's Hand  KFT  Warrior Used in the "infinite" Warrior decks that never fatigue, e.g. slow Tempo Warrior builds or Fatigue Warrior. Very niche card + the decks are hard to play, so not recommended for new players.
 Blazecaller  Un'Goro  Neutral Sometimes seen in the Elemental decks, like Elemental Shaman. Might be okay option for new players, but the Elemental decks get obsolete quite quickly.
 Bright-Eyed Scout  Un'Goro  Neutral 1 copy. Sometimes used in Ramp Druid, which runs a lot of 6+ mana cards, to fetch a card with a mana discount. Bad in most of the decks.
 Crazed Worshipper (*)  Old Gods  Neutral Can be played in some C'Thun decks. C'thun decks are generally good for new players, and so keeping a Worshipper might not be a bad idea if you're building one.
 

E Tier

If you haven't found the card you want to craft above, it means that it belongs to the last Tier - E Tier. Those cards aren't worth crafting. They aren't really good choices in the budget decks, they are overshadowed by better cards and they aren't generally useful right now. It doesn't mean that they're completely useless - sometimes a E Tier card gets support in a new expansion and jumps even as high as Tier A or B. Other times a new deck emerges that runs it as a tech card and it might become a D Tier card. Some of those cards might also be used in off-meta, "fun" decks, so if you like one in particular, there is nothing wrong with crafting it. You just need to understand that it's not and it's very likely to never be a competitive card.

Disclaimer: This Tier Lists are subject to change every time the meta changes. Since we're still pretty early into the current expansion (less than 20 days at the time I'm writing this), some of the higher tier cards might get shifted down, and vice versa. Maybe even a deck that contains an E Tier card will get discovered and this card will skyrocket in popularity. Take everything here with a grain of salt, and most importantly - use your own common sense when crafting cards.
