Animation Module + Securitron Squadron + Ashnod's Altar

Animation Module

Securitron Squadron

Ashnod's Altar

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, Securitron Squadron triggers, putting a +1/+1 counter on the Servo.
4. Animation Module triggers, holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
5. Resolve the Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
6. Repeat from step 3.

This crafty assembly turns a single +1/+1 counter into an endless factory of mechanical life and raw energy. Securitron Squadron serves as the linchpin, passively bestowing a +1/+1 counter upon every incoming creature token to instantly trigger Animation Module's first ability. By funneling the resulting Servo tokens directly into Ashnod's Altar, you generate more than enough colorless mana to continuously pay Animation Module's {1} fee, sustaining a self-perpetuating loop that yields infinite sacrifices, enters-the-battlefield events, and mana.
