How it works
Gain life.
The creature with Sunbond attached triggers, putting a +1/+1 counter on it.
Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
When the Servo enters, Prosperous Innkeeper triggers, causing you to gain life.
The creature with Sunbond attached triggers. Holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
Resolve the trigger from the creature with Sunbond attached, putting a +1/+1 counter on it
Repeat from step 3.
This looping engine is masterminded by Sunbond, turning every instance of life gain into a +1/+1 counter on your enchanted creature. That counter immediately tickles Animation Module to let you pay {1} for a Servo token, whose entrance prompts Prosperous Innkeeper to give you the life you need to restart the cycle. Meanwhile, Ashnod's Altar stands ready to sacrifice that freshly minted Servo for two colorless mana, ensuring you always have the {1} required to keep Animation Module churning out tokens while generating a surplus of mana.
