Legendary Creature — Human Minion
All Nightmares get +1/+1. {B}{B}{B}, Pay 3 life: Put target creature card from a graveyard onto the battlefield under your control. That creature is black and is a Nightmare in addition to its other creature types. When Chainer leaves the battlefield, exile all Nightmares.
“Reanimate Nightmares from your graveyard with a growing army of black threats.”
Chainer, Dementia Master is a graveyard-powered reanimation engine that turns your discard pile into an army of Nightmares. You fill your graveyard early through discard outlets, mill effects, and self-mill, then use Chainer's activated ability to reanimate creatures as black Nightmares. Each creature that hits the board gets a +1/+1 boost from Chainer, making your reanimated threats immediately relevant. The deck wins through aggressive reanimation, swinging with a growing army of Nightmares while Chainer himself grows stronger.
Your core game plan is to abuse cheap graveyard fillers and discard outlets to stock your graveyard quickly, then convert that resource into a continuous stream of threats. Cards like Faithless Looting, Stitcher's Supplier, and Zombie Infestation help you fill the yard, while Chainer's repeatable reanimation lets you get value from creatures multiple times. Late game, you're threatening lethal with an evasive, growing board while your opponents struggle to interact with creatures that keep coming back from the yard.
The main weakness is Chainer's vulnerability—if he leaves the battlefield, your entire team exiles, so protect him and be mindful of instant-speed removal. Build around creatures with enter-the-battlefield effects or those that generate value before they can be removed, maximizing each reanimation cycle.

Skip the expensive tutors; use efficient discard like Faithless Looting and Insolent Neonate instead of pricey alternatives, and lean on mid-range reanimation targets rather than chase mythic creatures.
