Hearthpwn

This is how I beat the deck that thinks it's a good idea to draw an additional card every turn. The Defender of Argus should probably be Sunfury Protector. These along with the Mark of the Wilds and Poison Seeds give you a way to get rid of the spectral guys that ping you. Naturalize can also do this in a pinch. I even blew up my own Dancing Swords just to draw him an additional card. 

Also good to know: he always draws first, even if he has no cards in his deck. Good luck!
