Loremaster Cho for Demon Hunters/ unsuspecting paladins/mages

Otherwise use Cho to mill your Obelisk quest if you dont have an aggro deck you are up against. Works great on mages to fill thier hand with unusable cards .

Take loremaster cho and use Grave Rune for true chaos.

Other than those feats-  Build up  Kharhut Defenders and Convincing Infiltrators with Shadowy Figure to clone them and build up a defense that even an aggro demon hunters and murloc decks cant counter.

Then sit around and heal them and yourselves while you watch them empty handed try everything they have then quit.
