Here's a list I copied from today's Boarcontrol's stream. It's like the old galakrond warlock with 26 cards being the same but the addition of Mo'arg Artificer and Rain of Fire is a big plus for board clears.

It's ofc extremely strong against Demon Hunter (Sacrificial Pact is in the deck) just as every other Warlock archetypes.

Thing is the multptiple board clear options make this deck extremely consistent in every other match up, including spell druid, and Galakrond, the Wretched, Zephrys the Great and [Hearthstone Card (Dragonqueen Alexstrasza) Not Found] can always give you the win in late game.

(Note : galakrond's battlecry seems to have much stronger outcomes in this extension -funnily enough the best demon you'll get will be DH demons :D)

Went 9-0 to get to legend with this deck (new system is soooo fast!) give this deck a try!

proof (cause there is always someone asking for it)
