Animation Module + Sigil Captain + Thermopod

Animation Module

Sigil Captain

Thermopod

How it works

1. Put a +1/+1 counter on a creature you control.
2. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
3. When the Servo enters the battlefield, Sigil Captain triggers, putting two +1/+1 counters on the Servo.
4. Animation Module triggers, holding priority, activate Thermopod's second ability by sacrificing the Servo, adding .
5. Resolve the Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
6. Repeat from step 3.

This clever loop turns Animation Module's counter-creation into a self-sustaining engine by relying on Sigil Captain to automatically pump out +1/+1 counters whenever a fresh Servo arrives as a 1/1. Those counters trigger the Module all over again to keep the token generation going, while Thermopod provides a reliable outlet to turn those expendable Servos into red mana for the loop's ongoing costs.
