Here's a card that will give a new definition to the Burn decks.
Thunderkin Awakener synergizes with Ball Lightning, Groundbreaker, Lightning Skelemental, and Ashenmoor Liege. All these cards are meant for fast damage, which the Awakener can easily double up.
If Thuderkin gets killed, then just use Unearth to bring it back and attack once again for another seven points of damage.
The only thing that could prevent this plan from working is the graveyard hate, such as Leyline of the Void. But that doesn't prevent Dredge decks from being in the top tier, so why worry?
