Animation Module + Boomer Scrapper + Phyrexian Altar

Animation Module

Boomer Scrapper

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing a creature, adding 1.
2. When the creature leaves the battlefield, Boomer Scrapper's second ability 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. Repeat.

This clever loop centers on Boomer Scrapper, which grows stronger whenever a token leaves the battlefield and naturally provides fuel through its own Junk tokens, though here we bypass them to focus on sacrifice value. By feeding creatures into Phyrexian Altar, you generate the exact mana needed to pay Animation Module's triggered ability, which responds to the +1/+1 counter placed on Boomer Scrapper by creating a fresh Servo token. Because sacrificing the Servo triggers Boomer Scrapper all over again, this creates a seamless, self-sustaining engine for infinite power, death, and sacrifice triggers.
