Animation Module

Ashnod's Altar

Cleric Class

Verdant Sun's Avatar

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, Verdant Sun's Avatar 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 spins into motion the moment you gain life, turning Cleric Class into a continuous engine that hands out +1/+1 counters to your creatures. Each of those counters wakes up Animation Module, which invites you to spend a single mana to forge a 1/1 Servo artifact creature token. That new token's arrival immediately triggers Verdant Sun's Avatar to hand you more life, feeding right back into Cleric Class to keep the chain unbroken. Meanwhile, sacrificing that Servo to Ashnod's Altar supplies all the colorless mana you need to pay for Animation Module's trigger, leaving you with an endless surplus of life, triggers, and resources.
