Hearthpwn

I would drop 1 card and pick up Windfury. The burst from it paired with Rockbiter Weapon on any card can be game changing. I would also drop the Big Game Hunter for Leeroy Jenkins. You already have 2 hexes and Black Knight for dealing with bigger minions. Leeroy is great for finishing the game.. It doesn't need to be a Leeroy + Windfury combo. It could be Leeroy + Faceless or Leeroy + Rockbiter + Flametounge totem. I have even droped Leeroy on turn 7 because I was going to use lightning storm anyway.
