This is the best version of the deck I could come up with. Not competitive but still a fun deck, if just for the sake of a very satisfying OTK, and giving play to getting less commonly used cards like Deathwing and Majordomo Executus from the blackrock mountain solo adventure.

The combo : Aviana > Innervate (or previously Thaurissan reduced)> Kun the Forgotten King > Clockwork Automaton > Carnivorous Cube the Automaton > Faceless Manipulator the cube > play Majordomo Executus > Play Deathwing > Hero power.

Note : if opponent has reborn or deathrattle minions like Voidlord on board, the burst damage isn't guaranteed to go face, so make sure you use poison seeds on the them the turn before.

The combo is 8 card for 128 damage, or 7 cards for 32 dmg if you don't faceless the cube
