How it works
Gain life.
Cleric Class triggers, putting a +1/+1 counter on a creature you control.
Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
When the Servo enters, Trostani triggers, causing you to gain life.
Cleric Class triggers. Holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
Resolve the Cleric Class trigger, putting a +1/+1 counter on a creature you control.
Repeat from step 3.
This clever loop turns a single instance of life gain into a self-sustaining engine of growth and mana. With Cleric Class at level 2 boosting your life gain and Trostani, Selesnya's Voice translating every new body into more life, you create a seamless feedback loop: Trostani's lifegain triggers Cleric Class to place a +1/+1 counter, which in turn triggers Animation Module to spawn a Servo token. Because Krark-Clan Ironworks can sacrifice that Servo for colorless mana before the next counter resolves, you easily pay Animation Module's tax while profiting on mana, all while infinitely pumping your creatures and generating endless artifact sacrifices.
