Mono-shadow Evenhanded Golem deck built for gauntlets. Between Golem, Incarnus, and Veteran Mercenary, we have a bunch of units that provide a ton of card advantage, plus 4 last chance and 4 immortalize to reuse Incarnus and Mercenary. Fell Ritual and Piercing Grief also synergize quite well with the void returns.
EDIT: Swapped out the top end and made the deck lower to the ground. The Incarnus and especially Desecrate nerfs were pretty bad for the deck; making do with annihilate but it's definitely a big hit.
