Animation Module + Ashnod's Altar + Snapping Sailback + Pandemonium

Animation Module

Ashnod's Altar

Snapping Sailback

Pandemonium

How it works

1. Put a +1/+1 counter on a creature you control.
2. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
3. When the Servo enters the battlefield, Pandemonium triggers, dealing 1 damage to Snapping Sailback.
4. Snapping Sailback triggers, holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
5. Resolve the Snapping Sailback trigger, putting a +1/+1 counter on it.
6. Repeat from step 2.
7. Once you have infinite mana, you may forego sacrificing the Servo tokens.

This clever loop transforms a single ping into a self-sustaining engine of creation and destruction, all fueled by Pandemonium letting your newly arrived tokens strike your own creatures. Whenever a Servo token enters the battlefield, Pandemonium deals 1 damage to Snapping Sailback, which triggers the dinosaur's enrage ability to grow larger with a +1/+1 counter. That counter in turn wakes up Animation Module, allowing you to pay the {1} mana required to pop out another Servo token and keep the cycle spinning. Ashnod's Altar acts as the financial engine of the operation, sacrificing each freshly minted Servo to generate two colorless mana—more than enough to pay the Module's tribute and leave you with an ever-growing surplus of infinite mana, tokens, and power.
