Cass, Hand of Vengeance + Thermopod + Ajani's Chosen

Cass, Hand of Vengeance

Thermopod

Ajani's Chosen

How it works

1. Activate Thermopod by sacrificing another creature that has an Aura attached to it.
2. When the creature dies, Cass triggers, returning an Aura that was attached to the creature from your graveyard to the battlefield attached to another creature you control.
3. When the Aura enters the battlefield, Ajani's Chosen triggers, creating a creature token.
4. Repeat.

This fiery loop revolves around sacrificing a creature outfitted with an Aura to Thermopod, generating red mana while sending the creature and its attachment to the graveyard. That death triggers Cass, Hand of Vengeance, whose ability plucks the Aura right back out of the graveyard and slaps it onto another creature you control. The moment that Aura re-enters the battlefield, Ajani's Chosen springs into action to generate a fresh 2/2 Cat token, providing a brand-new target to receive the returning Aura and fuel the sacrifice engine all over again.
