Animation Module + Light of Promise + Anointer Priest + Phyrexian Altar

Animation Module

Light of Promise

Anointer Priest

Phyrexian Altar

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, Anointer Priest triggers, causing you to gain life.
5. The creature with Light of Promise attached triggers. Holding priority, activate Phyrexian Altar by sacrificing the Servo, adding 1.
6. Resolve the trigger from the creature with Light of Promise attached, putting a +1/+1 counter on it
7. Repeat from step 3.

This delightful loop transforms a simple spark of life into an unstoppable engine of growth and sacrifice. With Light of Promise enchanting a creature, any initial lifegain triggers that creature to grow, which simultaneously awakens Animation Module to offer a Servo token for a single mana. That entering token triggers Anointer Priest to return the favor with more life, looping the Light of Promise trigger back onto the stack. By feeding the newly minted token to Phyrexian Altar right when you need it, you generate the exact mana required to pay for Animation Module's trigger, sustaining an endless cycle of infinite life, counters, and sacrifices.
