Hi guys. 

I am convinced this is the best version of DH right now. The reason to this is huge amount of tempo and damage you can get early to mid game. Other DH decks tend to run Nzoth and yes, while it is good to ressurect 8/8 demon, Nzoth is a dead card until turn 10. Also, because of Nzoth people run bad cards like 4/3 murloc. The thing is: if you play more aggressive early game, you dont need that extra 8/8 demon from Nzoth. 

Card Choice: 

Instead I play 3 mana Felsteel Executioner that are amazing out of Skull and the new sigil that is superb both defensively and offensively. I also run Cult Neophyte to disrupt your opponent powerturns to gain tempo. That is super good vs priest, mage, rogue or druid. I also play Kurtrus Ashfallen cause its very good in current meta where everything has 2-3 attack and also can corrupt weapon. My tech card is the Magehunter. It is amazing against priests, paladins and warriors turtle.  

Mulligan: 

Mulligan is pretty easy here. You want deathrattle combos, 1/2 weapon or sigil. Sometimes I keep Illidari Studies with coin and Skull to coint it out on 4. 

Matchups:

Mirror: You have much better chances cause they play bad cards and you play magehunter that disrupts their deathrattle chain.

Mage: Havent seen them since WC

Warrior: Favorable. You push them super hard from start, silence their turtle if possible

Hunter: Favorable. THe sigil is super good here

Rogue: Tough, they have better tempo, but if you focus on face and let them make trades you should be fine

Shaman: you can out-tempo them, disrupt their turns with Cult Neophyte
Druid: 

Druid: Always keep high pressure on face and disrupt key turns with Cult

Priest: Always clear their board, 1 mistake = they full heal

Paladin: You also out tempo them, bypass nasty taunts with Magehunter

Warlock: Usually a very good matchup

Enjoy guys, let me know your experience!
