Battalion Foot Soldier + Phyrexian Altar + Wheel of Sun and Moon + Animar, Soul of Elements

Battalion Foot Soldier

Phyrexian Altar

Wheel of Sun and Moon

Animar, Soul of Elements

How it works

1. Cast Battalion Foot Soldier by paying .
2. Animar triggers, putting a +1/+1 counter on itself.
3. When Battalion Foot Soldier enters the battlefield, it triggers.
4. Holding priority, activate Phyrexian Altar by sacrificing Battalion Foot Soldier, adding .
5. Battalion Foot Soldier is put on the bottom of your library instead of into your graveyard due to Wheel of Sun and Moon.
6. Resolve the Battalion Foot Soldier trigger from step 2, searching your library for Battalion Foot Soldier and putting it into your hand.
7. Repeat.

This clever loop turns the humble Battalion Foot Soldier into an infinite engine by leveraging a clever replacement effect from Wheel of Sun and Moon, which ensures your sacrificed soldier never truly leaves the library. With Animar, Soul of Elements on the board, each iteration not only grows Animar's power with free +1/+1 counters but also reduces the soldier's casting cost to zero, allowing you to replay it endlessly from your hand. Finally, Phyrexian Altar acts as the sacrificial heart of the operation, converting your looping soldier into the white mana needed to recast it while feeding endless death and entry triggers.
