Chainer, Dementia Master (CMM-144) is a legendary black creature from Commander Masters that supports Nightmare tribal and reanimation strategies. It gives all Nightmares +1/+1 and can pay {B}{B}{B} and 3 life to return a creature card from a graveyard as a black Nightmare under your control. When it leaves the battlefield, it exiles those returned Nightmares, creating a risk-reward timing element for persistent value.
