Animation Module + Ashnod's Altar + Cleric Class + Ajani's Welcome

Animation Module

Ashnod's Altar

Cleric Class

Ajani's Welcome

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, Ajani's Welcome triggers, causing you to gain life.
5. Cleric Class triggers. Holding priority, activate Ashnod's Altar 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 self-sustaining loop spins out of control the moment a single spark of life hits the board, turning trivial life gain into an unstoppable engine. It starts with Cleric Class, whose Level 2 static ability pumps out a +1/+1 counter every time you gain life, which in turn triggers Animation Module to offer a Servo token for a single mana. As that Servo enters the battlefield, Ajani's Welcome immediately triggers to give you more life—amplified by Cleric Class's built-in life-boosting replacement effect—which feeds right back into the enchantment. Finally, Ashnod's Altar acts as the financial engine of the operation, letting you sacrifice the newly minted token to generate more than enough colorless mana to pay the Animation Module's fee while keeping the infinite chain of triggers rolling forever.
