Cass, Hand of Vengeance + Umbral Collar Zealot + Ajani's Chosen

Cass, Hand of Vengeance

Umbral Collar Zealot

Ajani's Chosen

How it works

1. Activate Umbral Collar Zealot 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. Resolve the Umbral Collar Zealot ability.
5. Repeat.

This clever loop turns the graveyard and battlefield into a self-sustaining recycling center, fueled by the sacrifice outlet of Umbral Collar Zealot. When you feed an enchanted creature to the Zealot, Cass, Hand of Vengeance spots the death of an enchanted creature and immediately plucks the fallen Aura straight out of your graveyard, slapping it back onto the battlefield. That re-entering Aura acts as the spark for Ajani's Chosen, whose static ability triggers to churn out a fresh 2/2 Cat token ready to bear the weight of the enchantment—and leave you with a fresh vessel to sacrifice back to Umbral Collar Zealot all over again.
