Animation Module + Light of Promise + Healer of the Pride + Phyrexian Altar

Animation Module

Light of Promise

Healer of the Pride

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, Healer of the Pride 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.
