Mecha’thun Warlock

A control warlock shell that then looks to combo with Mecha'thun.

The combo is have Grim Rally +  Shriek  + Plot Twist + Dollmaster Dorian + Mecha'thun in your hand with nothing else and nothing in your deck. You then play Dorian and then plot twist. You then use Grim Rally on your Dorian and finally play shriek, discarding your Mecha’thun and winning the game.
