Arahbo, the First Fang + Whitemane Lion + Phyrexian Altar + God-Eternal Oketra

Arahbo, the First Fang

Whitemane Lion

Phyrexian Altar

God-Eternal Oketra

How it works

1. Cast Whitemane Lion by paying 1.
2. God-Eternal Oketra triggers, creating a 4/4 Zombie Warrior creature token.
3. When Whitemane Lion enters the battlefield, it and Arahbo trigger.
4. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
5. Resolve the Arahbo trigger, creating a 1/1 Cat creature token.
6. Activate Phyrexian Altar twice by sacrificing the Cat and Zombie Warrior, adding 1.
7. Repeat.

This loop turns a simple self-bouncing cat into an entire army thanks to the continuous token-generating engine provided by Arahbo, the First Fang and God-Eternal Oketra. As Whitemane Lion repeatedly enters and leaves the battlefield, it triggers Arahbo's ability to spawn a 1/1 Cat while constantly bouncing itself back to your hand for reuse, while God-Eternal Oketra rewards each cast of that creature spell with a hearty 4/4 Zombie Warrior. Finally, Phyrexian Altar acts as the crucial sacrifice outlet that converts those generated tokens into the exact mana needed to recast the Whitemane Lion, sustaining the loop indefinitely.
