Animation Module + Pitiless Plunderer + Carrion Feeder

Animation Module

Pitiless Plunderer

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing another creature.
2. When the creature dies, Pitiless Plunderer triggers, creating a Treasure token.
3. Activate the Treasure by tapping and sacrificing it, adding 1.
4. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
5. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
6. Repeat.

This clever loop turns the cycle of life and death into a self-sustaining engine, centered around Carrion Feeder as it hungrily devours your creatures to grow larger with a +1/+1 counter. Each time a sacrifice feeds the Feeder, Pitiless Plunderer steps in to salvage a Treasure token from the remains, providing the exact mana needed to keep going. The real secret to the loop is Animation Module, which watches for those counters being placed on Carrion Feeder and gladly trades a single mana to forge a brand-new Servo artifact creature token—ready to be sacrificed right back to the Feeder to start the cycle anew.
