Animation Module + Sunbond + Phyrexian Altar + Prosperous Innkeeper

Animation Module

Sunbond

Phyrexian Altar

Prosperous Innkeeper

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

This loop creates a self-sustaining engine of life and iron, where every drop of vitality feeds right back into the machinery. It all begins when Prosperous Innkeeper and a creature enchanted with Sunbond set the stage: gaining life pumps that enchanted creature full of +1/+1 counters, which in turn trips Animation Module's trigger to manufacture a fresh Servo token. Each new Servo makes the Innkeeper smile with more life gained, while Phyrexian Altar stands ready to sacrifice that very same Servo to feed the mana needed to keep Animation Module churning.
