Raging Worgen + Charge + Inner rage
(3 + 3 + 0 mana)
Basically, this combo allows you to do SIXTEEN DAMAGE with an 8/2 Windfury/Charge minion on turn six, the earliest it can be played (Turn 5 if you have the coin) which is just !@#$%^- ridiculous. it might not be OTK, but it most certainly is something to be feared. GG guys.
