Long Feng, Grand Secretariat + Animation Module + Phyrexian Altar

Long Feng, Grand Secretariat

Animation Module

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing any other creature you control, adding 1.
2. When the creature dies, Long Feng triggers, putting a +1/+1 counter on a creature you control.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. Repeat.

This clever loop turns the cycle of life and death into a self-sustaining engine by tying creature generation directly to the graveyard. When you sacrifice a creature to Phyrexian Altar, its death triggers Long Feng, Grand Secretariat to place a +1/+1 counter on one of your creatures. That counter instantly awakens Animation Module's passive trigger, allowing you to spend the mana you just generated to create a brand new 1/1 Servo artifact creature token ready to be sacrificed right back into the altar.
