Warren Soultrader + Gravecrawler + Susurian Voidborn

Warren Soultrader

Gravecrawler

Susurian Voidborn

How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing Gravecrawler.
2. When Gravecrawler dies, Susurian Voidborn triggers, causing you to gain 1 life and target opponent to lose 1 life.
3. Resolve the Warren Soultrader ability, creating a Treasure token.
4. Activate the Treasure by tapping and sacrificing it, adding .
5. Cast Gravecrawler from your graveyard by paying .
6. Repeat.

This gruesome little loop turns an endless parade of the undead into a fatal drain on your opponents, all fueled by the insidious value of Warren Soultrader. By sacrificing Gravecrawler to the Soultrader, you trigger Susurian Voidborn's passive drain-and-gain ability while generating a Treasure token to fund the exact mana needed for recasting. Because Gravecrawler can be cast straight from the graveyard as long as you control another Zombie, the Soultrader itself conveniently maintains that Zombie typing to keep the loop self-sustaining. The warp cost on Susurian Voidborn isn't even necessary here; its mere presence on the battlefield ensures that every single sacrifice effortlessly bleeds your target opponent dry.
