Animation Module + Ashnod's Altar + Cleric Class + Dazzling Angel

Animation Module

Ashnod's Altar

Cleric Class

Dazzling Angel

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, Dazzling Angel 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 loop turns a single instance of life gain into an endless, self-sustaining loop by weaving together counters, token generation, and sacrifice. It all kicks off when Cleric Class triggers from your initial life gain, which puts a +1/+1 counter onto a creature to wake up Animation Module; paying the module's fee creates a Servo token that immediately triggers Dazzling Angel to give you back your life. While that new Cleric Class trigger waits on the stack, you can sacrifice the Servo to Ashnod's Altar to generate the colorless mana needed to fund Animation Module's trigger repeatedly.
