So in addition to my last deck that I posted, I wanted to add Horde Operative + Big Game Hunter. That counters Paladin and Operative counters Mages and Paladin, plus it recently helped me vs an Evolve shaman that I could shot his 10 mana minion.

I prefer 3 mana Acrobatics rather than 6 mana Gul'dan cause it's a cheaper way of drawing cards early when you need them (and not on 6 mana when you have a full hand).

I put in Expandable performers instead of Priestess of fury, the priestess is not really competitive it's just good if you're already ahead which is rare with DH. Besides, I figured I managed to kill my opponent either way if I just survived a few more rounds. 

Lone Champion is something every Lifesteal DH should have in my opinion. It's a new card and it's really powerful often blocking 3 attacks that otherwise would have gone face. So you can throw it out on 3 mana and it stops all rushes and give you some space to get to 5 mana and Chaos Nova.

I added Sigil of Silence just now to try it, its a way of dealing with Paladin as well, you can secure a lethal blow with it if you cast it the turn before to remove all taunts that are incoming, and then you just throw out Illidari Inquisitor on 8 mana. (make sure to save one hit on your weapon on 7 mana. So rather not attack turn 7 to get 4+8 dmg to turn 8.
