Chainer, Dementia Master

$0.32

For {B}{B}{B} and 3 life, Chainer puts a creature card from any graveyard onto the battlefield under your control as a black Nightmare, and all Nightmares get +1/+1. The catch is that when Chainer leaves, every Nightmare gets exiled. Mono-black makes the mana easy: Cabal Coffers and a heavy Swamp count let you activate several times a turn. The deck fills graveyards with self-mill and discard, uses removal and wipes to supply even more targets, and reanimates value creatures and drain effects to grind the table down.

In the recorded games, Buried Alive set up the graveyard early, and Cabal Coffers with Thran Dynamo produced enough mana for repeated activations. Gray Merchant of Asphodel was the main drain, and sacrifice outlets like Viscera Seer and Altar of Dementia kept recycling creatures. Oblivion Stone and Life's Finale reset boards in its favor, and Massacre Wurm and Meteor Golem swung fights. Chainer recovered well after wipes. It lost ground when opponents countered activations or exiled Chainer, since all its Nightmares went with it, and milling or graveyard hate cut its fuel.
