Animation Module + Krark-Clan Ironworks + Light of Promise + Pious Evangel // Wayward Disciple

Animation Module

Krark-Clan Ironworks

Light of Promise

Pious Evangel // Wayward Disciple

How it works

1. Gain life.
2. The creature with Light of Promise 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, Pious Evangel triggers if it's on the battlefield.
5. Regardless, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC
6. When the Servo dies, Wayward Disciple triggers if it's on the battlefield.
7. Resolve either the Pious Evangel or Wayward Disciple trigger, causing you to gain life and target opponent to lose 1 life if Wayward Disciple triggered.
8. Repeat from step 2.

This elegant loop transforms a single instance of lifegain into a self-sustaining engine by tying +1/+1 counters directly to artifact production. Once your creature enchanted with Light of Promise receives a counter, Animation Module invites you to spend a single mana to generate a Servo, which Pious Evangel acknowledges upon entering the battlefield. You then feed that very Servo to Krark-Clan Ironworks to generate the two colorless mana you need to pay for Animation Module's trigger and keep the loop spinning with profit to spare. Finally, if Pious Evangel is transformed into Wayward Disciple, its death trigger turns every sacrificed artifact into life gained and opponent life lost, closing the loop into a lethal storm of triggers.
