Animation Module + Pitiless Plunderer + Bloodflow Connoisseur

Animation Module

Pitiless Plunderer

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur 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 elegant loop turns a simple sacrifice outlet into a self-sustaining engine by closing the mana loop. Bloodflow Connoisseur acts as the core engine, turning expendable bodies into growth, while Pitiless Plunderer refunds your investment by generating a Treasure token every time a creature dies. The mana from that Treasure pays right back into Animation Module, which turns the +1/+1 counter placed on the Connoisseur into a fresh Servo token. Because the Servo itself becomes your next sacrifice victim, the entire assembly perpetually feeds itself to generate an endless cascade of artifacts, counters, and death triggers.
