Blight Mound + Umbral Collar Zealot + Reassembling Skeleton + Pitiless Plunderer

Blight Mound

Umbral Collar Zealot

Reassembling Skeleton

Pitiless Plunderer

How it works

1. Activate Umbral Collar Zealot by sacrificing Reassembling Skeleton.
2. When Reassembling Skeleton dies, Pitiless Plunderer and Blight Mound trigger, creating a creature token and a Treasure token.
3. Resolve the Umbral Collar Zealot ability.
4. Activate Umbral Collar Zealot by sacrificing the creature token.
5. When the creature token dies, it and Pitiless Plunderer triggers, creating a Treasure token and causing you to gain 1 life.
6. Resolve the Umbral Collar Zealot 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 loop turns a modest graveyard dweller into an engine of endless value by pairing Pitiless Plunderer with Blight Mound to refund every sacrifice with both a Treasure and a Pest token. As you repeatedly feed creatures to Umbral Collar Zealot, Pitiless Plunderer's triggered ability provides the exact mana needed to bring Reassembling Skeleton right back to the battlefield from your graveyard. Meanwhile, Blight Mound and Umbral Collar Zealot ensure that every cycle of death and recycling not only generates a steady stream of life and life-linked tokens, but also fuels an infinite stream of surveil triggers to sculpt your draw.
