Mazzy, Truesword Paladin + Phyrexian Altar + Chishiro, the Shattered Blade

Mazzy, Truesword Paladin

Phyrexian Altar

Chishiro, the Shattered Blade

How it works

1. Activate Phyrexian Altar by sacrificing the creature with the Aura attached, adding one mana of any color.
2. Mazzy's second ability triggers, exiling the Aura and allowing you to cast it until your next turn.
3. Cast the Aura from exile by paying its mana cost, attaching it to any other creature you control.
4. When the Aura enters, Chishiro triggers, creating a creature token.
5. Repeat.

This loop hinges on a clever recycling cycle fueled by Phyrexian Altar, which lets you sacrifice a creature wearing an Aura to generate mana. Once the creature hits the graveyard, Mazzy, Truesword Paladin steps in to exile the Aura and grant you permission to cast it from exile right back onto the battlefield. Re-casting that Aura safely satisfies Chishiro, the Shattered Blade, whose enter-the-battlefield trigger continuously produces a fresh 2/2 Spirit token to feed right back to the Altar.
