In this video Thijs shows you how to play OTK Warrior with Worgen 
Combo. This is a viable ladder and tournament deck. The deck consists of a lot of card cycling cards to find the combo pieces. Then you want to land a well-placed Emperor Thauissan to discount all your combo pieces.
You are looking to play:
Raging Worgen + Charge + Inner Rage
This gives you ann 8/3 with windfury!
Use Faceless Manipulator and you have two 8/3’s!
You can do all of this for 10 mana as you weill see in the video below.
