Animation Module + Serra Redeemer + Thermopod

Animation Module

Serra Redeemer

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, Serra Redeemer 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 the humble Animation Module into an infinite manufacturing plant by exploiting the generous trigger on Serra Redeemer. Every time a new creature enters with power 2 or less, Serra Redeemer rushes in to drop a pair of +1/+1 counters on it, which in turn wakes up Animation Module's first ability to birth a fresh Servo artifact creature token for just one mana. To sustain the mana flow and clear the board for the next iteration, you simply feed that newly minted Servo to Thermopod, cashing it in for red mana to keep paying the Animation Module's recurring tax.
