Traveling Plague + Thermopod + Ajani's Chosen

Traveling Plague

Thermopod

Ajani's Chosen

How it works

1. Cast Traveling Plague by paying 3, attaching it to another creature you control.
2. When Traveling Plague enters, Ajani's Chosen triggers, creating a creature token.
3. Activate Thermopod by sacrificing the creature Traveling Plague is attached to.
4. When the creature dies, Traveling Plague triggers, returning itself from your graveyard to the battlefield attached to the token created in step 2.
5. When Traveling Plague enters, Ajani's Chosen triggers, creating a creature token.
6. Repeat from step 3.

This loop relies on an ingenious self-sustaining cycle of life and death fueled by Ajani's Chosen, which constantly populates the board with new Cat tokens whenever an enchantment enters. By using Thermopod as a reliable sacrifice outlet, you can send your currently enchanted creature to the graveyard, which immediately triggers Traveling Plague's recursion ability to return itself right back to the battlefield attached to your newly minted Cat. Every single iteration of this process generates a burst of red mana while repeating the entire cycle endlessly, making this a devastating engine in Commander, Legacy, Oathbreaker, and Vintage.
