Animation Module + Essence Warden + Sunbond + Phyrexian Altar

Animation Module

Essence Warden

Sunbond

Phyrexian Altar

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, Essence Warden 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 clever loop turns a single instance of life gain into an escalating chain of growth and recycling. Once your creature enchanted with Sunbond receives a trigger to grow, Animation Module rewards that counter by offering a Servo token for a single mana. That new arrival immediately alerts Essence Warden to bump your life total, which in turn fuels Sunbond all over again to keep the counters flowing. To sustain the mana needed for Animation Module's trigger, Phyrexian Altar steps in to sacrifice the freshly minted Servo for the exact {1} required, looping the entire process indefinitely.
