Animation Module + Krark-Clan Ironworks + Lunarch Veteran // Luminous Phantom + Sunbond

Animation Module

Krark-Clan Ironworks

Lunarch Veteran // Luminous Phantom

Sunbond

How it works

1. Gain life.
2. The creature with Sunbond attached triggers, putting a +1/+1 counter on it.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. When the Servo enters, Lunarch Veteran triggers if it's on the battlefield.
5. Regardless, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC
6. When the Servo dies, Luminous Phantom triggers if it's on the battlefield.
7. Resolve either the Lunarch Veteran or Luminous Phantom trigger, causing you to gain life
8. Resolve the trigger from the creature with Sunbond attached, putting a +1/+1 counter on it
9. Repeat from step 3.

This loop turns a single instance of life gain into a self-sustaining engine by turning every life point into an expanding web of triggers. Once Sunbond enriches your chosen creature, gaining life places +1/+1 counters on it, which Animation Module happily capitalizes on to manufacture a 1/1 Servo artifact creature token for a single mana. From there, Krark-Clan Ironworks steps in to sacrifice that newly minted Servo, refunding more than enough colorless mana to fuel the Animation Module while sending the Servo to the graveyard. This exit triggers Lunarch Veteran's front face or its Luminous Phantom back face to grant you more life, restarting the Sunbond cascade and letting you repeat the entire process indefinitely.
