This plays out just like normal Tempo Demon Hunter, but it has Archmage Vargoth to get a bit more value out of Metamorphosis, Skull of Gul'dan, and Eye Beam if he sticks around.

We've got a gameplay video against a Priest with 7 Khartut Defenders and 6 board clears showing just how far this deck can go. Check it out at https://youtu.be/2sjjVXk5jsQ if you're interested.

Enjoy!
