Battle of Hoover Dam + Animation Module + Phyrexian Altar

Battle of Hoover Dam

Animation Module

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing a creature, adding 1.
2. When the creature dies, Battle of Hoover Dam triggers, putting two +1/+1 counters 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 elegant little loop turns the Legion side of Battle of Hoover Dam into a self-sustaining engine of sacrifice and creation. Whenever a creature goes to the graveyard to feed Phyrexian Altar for mana, Battle of Hoover Dam triggers to pump up your board with +1/+1 counters. That counter placement immediately wakes up Animation Module, allowing you to pay the exact mana you just generated to produce a fresh 1/1 Servo artifact creature token ready to be sacrificed right back to the Altar.
