Deck CompositionThere are a huge number of Ramp Druid styles, but they all use a core set of powerful Druid class cards (and a hugely popular neutral legendary!):
2x Wild Growth
2x Keeper of the Grove
2x Druid of the Claw
1x The Black Knight
2x Ancient of Lore
The above 15 cards are the only truly 'default' inclusions in a standard Ramp Druid deck. There are a wide variety of variants, either designed around legendaries, heavy taunt minions, aggressive finishers, or high value mid-range minions. Common choices are:
Mark of the Wild
Big Game Hunter
Shade of Naxxramas
Force of Nature
Ancient of War
Ragnaros the Firelord
New! Some of the new Druid cards in Goblins vs. Gnomes may also fit the goal of this style, such as:
Tree of Life
Playstyle, Tips, and NotesNo big plays, no major surprises. Ramp Druid will remind you of playing Arena, almost - value, efficiency, and good trades are the objectives at almost every juncture. The suite of spells available is limited, and focuses on taking out aggressive players' low-health minions; the remainder of the deck is almost exclusively sticky minions (and, for many, the FoN/Roar finisher combo). Keep a weather eye on your opponent's potential board clears and what you have left in the bank for removal of your own.
MulligansIn every match up, you want to have Innervate and/or Wild Growth, but you'll keep other options based on your initial draw and opponent's class. If you start with The Coin, it's valid to fish for an Innervate and a 4-drop. For aggressive opponents, hold Wrath and/or a Swipe.
Combos and Counters
Ramp Druid is an easy deck to learn, because you're rarely fishing for complex combos. You mostly want to make the most efficient play you can per turn, and will only be able to play one card most turns. You'll struggle against classes that can push you into extended games where they have their own sticky minions, as your removal is primarily suited to early game trades.
