Aggro Token Druid
Aggro Token Druid is a long time archetype in Hearthstone. In the past it used the power of Innervate to accelerate out minions to create wide board states and overrun the opponent with a well-timed Savage Roar.
This deck grew extremely powerful after the Journey to Un’Goro expansion release. It added Vicious Fledgling, Living Mana, and Bittertide Hydra making it an extremely dangerous deck on the ladder.
Druid’s power came to an all-time high at the beginning of the Knights of the Frozen Throne meta. With Aggro Token and Jade Druid at the top of the game, this led to the nerf to the classic Druid card, Innervate. Even with these nerfs it only slowed this deck down a bit, and it remains powerful going into the Kobolds and Catacombs meta.
