How it works
Gain life.
Heliod 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 the battlefield, Haliya triggers, causing you to gain 1 life.
Heliod triggers, holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
Resolve the Heliod trigger, putting a +1/+1 counter on a creature you control.
Repeat from step 3.
This clever loop turns the simple act of gaining life into a self-sustaining engine of creation and transmutation. With Heliod, Sun-Crowned waiting to convert your lifegain into +1/+1 counters, Animation Module is primed to reward each counter by letting you pay {1} for a fresh Servo artifact creature token. Every time that Servo enters the battlefield, Haliya, Guided by Light triggers to grant you the life needed to restart Heliod, while Krark-Clan Ironworks stands ready to sacrifice the Servo for a tidy profit of colorless mana.
