Animation Module + Krark-Clan Ironworks + Cleric Class + Auriok Champion

Animation Module

Krark-Clan Ironworks

Cleric Class

Auriok Champion

How it works

1. Gain life.
2. Cleric Class triggers, putting a +1/+1 counter on a creature you control.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. When the Servo enters, Auriok Champion triggers, causing you to gain life.
5. Cleric Class triggers. Holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
6. Resolve the Cleric Class trigger, putting a +1/+1 counter on a creature you control.
7. Repeat from step 3.

This clever loop is powered by a continuous cycle of life and metal, kicking off whenever you gain life to trigger Cleric Class and place a +1/+1 counter on a creature. That counter immediately awakens Animation Module, allowing you to pay a single mana to spawn a fresh 1/1 Servo artifact creature token. The moment that token hits the battlefield, Auriok Champion gently nudges your life total upward, feeding right back into Cleric Class while the brand-new Servo is fed to Krark-Clan Ironworks to generate the colorless mana needed to sustain the entire loop.
