Gutter Grime + Reassembling Skeleton + Yahenni, Undying Partisan + Pitiless Plunderer

Gutter Grime

Reassembling Skeleton

Yahenni, Undying Partisan

Pitiless Plunderer

How it works

1. Activate Yahenni by sacrificing Reassembling Skeleton.
2. When Reassembling Skeleton dies, Pitiless Plunderer and Gutter Grime trigger, creating a creature token and a Treasure token.
3. Resolve the Yahenni ability.
4. Activate Yahenni by sacrificing the creature token.
5. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
6. Resolve the Yahenni ability.
7. Activate the Treasures by tapping and sacrificing them, adding 1.
8. Activate Reassembling Skeleton by paying 1, returning it from your graveyard to the battlefield.
9. Repeat.

This clever loop relies on Yahenni, Undying Partisan as your dedicated sacrifice outlet to continuously feed the engine. Each time you send Reassembling Skeleton to the graveyard, Pitiless Plunderer generates a Treasure token to help fund the Skeleton's return, while Gutter Grime scales into an ever-growing Ooze token that provides a fresh sacrifice target for Yahenni. As this cycle repeats, Yahenni grows infinitely large with +1/+1 counters, churning out endless death and sacrifice triggers to overwhelm your opponents.
