Discard a card: You may cast a creature spell from your graveyard this turn. Activate only once each turn.
Whenever a nontoken creature you control enters, if you didn't cast it from your hand, it gains haste until your next turn.
Fill your graveyard with powerful creatures, then loop them back onto the battlefield via Chainer's discard ability, getting free hasty attackers each turn. You generate card advantage and value by discarding cards you'd rather not cast and recasting big threats from the yard, then close games with reanimation payoffs and recursive beaters. Turn to turn you're sculpting your graveyard, swinging with haste, and grinding opponents out of resources.
Add fast mana (Dark Ritual, Jeska's Will) and premium discard outlets to activate Chainer earlier and more efficiently. Tighten the creature suite around high-impact ETBs and reanimation targets, and include a compact combo line like Worldgorger Dragon plus an Animate Dead effect. Round out with graveyard-hate protection and a couple of tutors to assemble your engine consistently.
