Pitiless Plunderer + Reassembling Skeleton + Umbral Collar Zealot + Teysa Karlov

Pitiless Plunderer

Reassembling Skeleton

Umbral Collar Zealot

Teysa Karlov

How it works

1. Activate Umbral Collar Zealot by sacrificing Reassembling Skeleton.
2. When Reassembling Skeleton dies, Pitiless Plunderer triggers twice, creating two Treasure tokens.
3. Resolve the Umbral Collar Zealot ability.
4. Activate the Treasure tokens by tapping and sacrificing them, adding 1.
5. Activate Reassembling Skeleton by paying 1, returning it from your graveyard to the battlefield tapped.
6. Repeat.

This elegant loop turns a persistent skeleton into an infinite engine for death and filtering by leveraging the explosive synergy of Teysa Karlov and Pitiless Plunderer. When you use Umbral Collar Zealot to sacrifice Reassembling Skeleton, Teysa Karlov doubles the death trigger, causing Pitiless Plunderer to generate two Treasure tokens instead of one. Sacrificing those Treasures easily pays the activation cost to bring Reassembling Skeleton right back to the battlefield, leaving you net-positive on mana and infinitely surveilling your deck.
