Captain America, Team Leader + Animation Module + Arcane Adaptation + Thermopod

Captain America, Team Leader

Animation Module

Arcane Adaptation

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 as a Hero due to Arcane Adaptation, Captain America triggers, putting a +1/+1 counter on it and the Servo.
4. Animation Module triggers twice.
5. Holding priority, activate Thermopod by sacrificing the Servo, adding .
6. Resolve the first Animation Module trigger, choosing not to pay.
7. Resolve the second Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
8. Repeat from step 3.

This ingenious loop turns a single +1/+1 counter into a self-sustaining engine of creation and sacrifice, fueled by Arcane Adaptation making every creature you own a Hero. That classification is crucial, because whenever a new token arrives, Captain America, Team Leader instantly grows stronger while bestowing another +1/+1 counter on that newcomer. That counter placement wakes up Animation Module to birth a fresh Servo artifact creature token, which you can immediately feed to Thermopod to generate the red mana needed to keep paying the Module's tribute.
