Animation Module + Ashnod's Altar + Light of Promise + Aunt May

Animation Module

Ashnod's Altar

Light of Promise

Aunt May

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, Aunt May triggers, causing you to gain life.
5. The creature with Light of Promise attached triggers. Holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
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 ingenious loop transforms a single instance of life gain into a self-sustaining engine of growth and resources. It all begins when Aunt May rewards a creature's entry by granting you life, which triggers Light of Promise to place a +1/+1 counter on its enchanted host—a change that immediately awakens Animation Module to forge a Servo artifact creature token for the low cost of one mana. As that new Servo enters the battlefield, Aunt May triggers once more to restart the cycle, while Ashnod's Altar stands ready to sacrifice the freshly minted token, converting it into the colorless mana needed to pay for the Module and net a profit of {C}.
