The pool of available Mage cards has somewhat shrunk following the launch of Journey to Un'Goro and the Year of the Mammoth Standard rotation. Cards like Arcane Blast, Forgotten Torch, Flame Lance and roughly three others can no longer be generated by Babbling Book, Cabalist's Tome and other RNG cards like them. Surprisingly, Un'Goro itself has more than made up for this fact, introducing six completely new spells. One of them, however, Open the Waygate can not be generated by random chance and is the main reason we're writing this post.
Taking two turns in a row is tremendously powerful in Hearthstone.
So powerful, in fact, that it has spawned new archetypes - Exodia Mage (Thijs' Un'Goro Exodia Mage) being the most common of them - and all players have to do is cast six spells that didn't start in their deck.
With the help of cgmcnama's spreadsheet, we've prepared a quick rundown of the cards. In short, we talk about the different ways to complete Open the Waygate and then highlight the possible outcomes for any "random Mage spell" card such as Babbling Book, Cabalist's Tome, and Primordial Glyph.
Generating Random Spells
So you want to generate random spells to help fulfill the Quests requirements, but where do you start?
Here are all the current cards that give you a random spell:
|1||Babbling Book||Cheap minion is a good bonus.||Yes|
|2||Primordial Glyph||Makes the spell itself cheaper. One of the best options.||Yes|
|2||Shimmering Tempest||A Deathrattle effect so can be countered.||Reasonable|
|2||Lorewalker Cho||Not guaranteed to activate.||No|
|3||Kabal Courier||Not guaranteed to be a spell.||No|
|3||Mana Bind||Opponent can play around this.||Reasonable|
|4||Kabal Chemist||Random potions aren't always the greatest, but not bad.||Reasonable|
|5||Burgly Bully||Yes, The Coin counts.||Reasonable|
|5||Cabalist's Tome||A very solid option.||Yes|
|6||Mukla, Tyrant of the Vale||Technically the bananas count.||No|
|7||Archmage Antonidas||Probably wouldn't want to, but these Fireballs should count.||No|
|9||Ysera||She generates Dream cards.||No|
Average Spell Cost
Interestingly, the average spell is actually almost four mana. With that in mind, it should on average take 24 mana, enough to consume nearly every mana crystal across your first seven turns. That's obviously unrealistic since you need to actually spend mana to generate those random spells, let alone the fact that you also have to worry about staying alive by answering your opponent's pressure.
Hopefully, the following table helps you understand the liklihood of being able to activate the Quest's effect on any given turn.
|3.52 Average Mana Cost|
Here is every possible Mage spell that can be generated from those three cards. While cheaper spells obviously help you reach six total faster, they might not be as useful in your efforts to get to that point.
