Arahbo, the First Fang + Whitemane Lion + Phyrexian Altar + Genesis Chamber

Arahbo, the First Fang

Whitemane Lion

Phyrexian Altar

Genesis Chamber

How it works

1. Cast Whitemane Lion by paying 1.
2. When Whitemane Lion enters the battlefield, it, Genesis Chamber and Arahbo trigger.
3. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
4. Resolve the Arahbo trigger, creating a 1/1 Cat creature token.
5. Resolve the Genesis Chamber trigger, creating a 1/1 Myr artifact creature token.
6. Activate Phyrexian Altar twice by sacrificing the Cat and Myr, adding 1.
7. Repeat.

This loop is a masterclass in self-sustaining feline logistics, turning the simple act of casting a cat into a perpetual engine of sacrifice. Every time you cast Whitemane Lion, its entry triggers Genesis Chamber to spawn a Myr and Arahbo, the First Fang to manifest a 1/1 Cat token, while the Lion's own ability forces itself right back to your hand for just {1}{W}. Meanwhile, Arahbo's static bonus and Phyrexian Altar work in tandem as the ultimate recycling plant; you simply feed the newly generated Cat and Myr tokens to Phyrexian Altar to recoup the exact mana needed to cast the Lion all over again.
