Hearthpwn

Two Elekks. If you don't create a copy of Elekk, you won't be able to use Plot Twist as a DMH after your only Elekk is cleared. Therefore, it's a DMH that requires 4 cards to be infinite (both Elekks and both Plot Twists) rather than 2 like original DMH.

Step 1: don't die before Gul'dan.

Step 2: Have a ton of armor on Gul'dan turn either by having a huge buffer that won't be taken away by doomguards or by saving a blackwald pixie in your hand)

Step 3: Reckless fury

Step 4: Tank up. Your opponent is most likely ahead of you in fatigue, so all you need to do is to outlast him.

Control lock with Rin gives this deck a world of trouble though, there's almost no draw.
