Pitiless Plunderer + Reassembling Skeleton + Umbral Collar Zealot + Mirror Room // Fractured Realm

Pitiless Plunderer

Reassembling Skeleton

Umbral Collar Zealot

Mirror Room // Fractured Realm

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 looping engine turns a humble skeleton into an infinite workshop by leveraging the double-trigger amplification of Mirror Room // Fractured Realm. When you sacrifice Reassembling Skeleton to Umbral Collar Zealot, Pitiless Plunderer sees the death and—doubled by the room's static enchantment effect—generates two Treasure tokens instead of one. Sacrificing those Treasures easily pays the activation cost to pull the Skeleton right back from the graveyard, leaving you with surplus mana and infinite loops of death, entry, and surveil triggers.
