Gravecrawler

Pitiless Plunderer

Umbral Collar Zealot

How it works

2. When Gravecrawler dies, Pitiless Plunderer triggers, creating a Treasure token.
3. Resolve the Umbral Collar Zealot ability.
4. Activate the Treasure token by tapping and sacrificing it, adding .
5. Cast Gravecrawler from your graveyard by paying .
6. Repeat.

This loop turns the graveyard into a tireless engine by using Umbral Collar Zealot to sacrifice Gravecrawler over and over, feeding your graveyard while digging deeper with surveil. Every time our relentless Zombie hits the dirt, Pitiless Plunderer springs into action to generate a Treasure token, refunding the exact mana needed to recast Gravecrawler right back from the graveyard. Because Gravecrawler's own self-recurring ability only asks that you control another Zombie, the whole loop feeds itself infinitely—churning out endless sacrifice triggers and storm count without ever running out of fuel.
