Animation Module + Pitiless Plunderer + Bartolomé del Presidio

Animation Module

Pitiless Plunderer

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio 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 Bartolomé del Presidio 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 loop turns a simple sacrifice into a perpetual motion machine by feeding on its own byproduct. When you use Bartolomé del Presidio to sacrifice a creature, Pitiless Plunderer steps in to generate a Treasure token upon that death, immediately providing the mana needed to keep going. That sacrifice also puts a +1/+1 counter on Bartolomé del Presidio, which trips Animation Module's first ability to forge a fresh Servo artifact creature token for the exact cost of the Treasure you just cracked. Because that Servo can be immediately fed back into Bartolomé del Presidio, the cycle spins endlessly to yield infinite death triggers, artifacts, and counters.
