Cass, Hand of Vengeance + Ajani's Chosen + Bloodflow Connoisseur

Cass, Hand of Vengeance

Ajani's Chosen

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur ability.
5. Repeat.

This loop hinges on a clever recursive recycling of Auras to endlessly feed your board state. By using Bloodflow Connoisseur to sacrifice an enchanted creature, you trigger Cass, Hand of Vengeance to pull that Aura right back out of your graveyard and slam it back onto the battlefield. That re-entry instantly wakes up Ajani's Chosen, which generates a fresh Cat token to catch the returning Aura—providing you with a brand new sacrifice fodder piece for Bloodflow Connoisseur to devour all over again.
