Pitiless Plunderer + Reassembling Skeleton + Umbral Collar Zealot + The Masamune

Pitiless Plunderer

Reassembling Skeleton

Umbral Collar Zealot

The Masamune

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 cunning loop turns the humble act of skeletal recursion into an infinite engine, powered entirely by a clever doubling effect. By feeding Reassembling Skeleton to Umbral Collar Zealot, you send the skeleton to the graveyard while leveraging The Masamune's ability to double the resulting death triggers. This synergy causes Pitiless Plunderer to generate two Treasure tokens instead of one whenever the skeleton falls. You then simply crack those Treasures for the mana needed to bring Reassembling Skeleton right back to the battlefield, fueling a perpetual cycle of sacrifice, profit, and deep library manipulation through surveil.
