Vohar, Vodalian Desecrator + Haunted One + Cauldron of Souls + Deceiver Exarch + Carrion Feeder

Vohar, Vodalian Desecrator

Haunted One

Cauldron of Souls

Deceiver Exarch

Carrion Feeder

How it works

1. Activate Vohar's first ability by tapping it.
2. Vohar triggers, giving creatures you control that share a creature type with it +2/+0 and undying until end of turn.
3. Resolve the Vohar ability from step 1, causing you to loot.
4. Activate Carrion Feeder by sacrificing Deceiver Exarch.
5. When Deceiver Exarch dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
6. When Deceiver Exarch enters the battlefield, it triggers, untapping Cauldron of Souls.
7. Resolve the Carrion Feeder ability from step 4, putting a +1/+1 counter on it.
8. Activate Cauldron of Souls by tapping it, giving Deceiver Exarch persist until end of turn.
9. Activate Carrion Feeder by sacrificing Deceiver Exarch.
10. When Deceiver Exarch dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
11. When Deceiver Exarch enters the battlefield, it triggers, untapping Vohar.
12. Resolve the Carrion Feeder ability from step 9, putting a +1/+1 counter on it.
13. Repeat.

This intricate loop hinges on overlapping recursion mechanics, fueled by Vohar, Vodalian Desecrator pulling double duty as a looting engine and—thanks to the background buff from Haunted One—a granter of undying whenever it taps. By sacrificing Deceiver Exarch to Carrion Feeder, you trigger undying to bring the Exarch back, whose entry trigger untaps Cauldron of Souls. You can then use the Cauldron to grant the Exarch *persist*, allowing you to sacrifice it again so that its persist trigger brings it back with a -1/-1 counter; because it had no +1/+1 counters left from the previous recursion, the two counters cleverly cancel each other out, resetting the cycle entirely. As Deceiver Exarch bounces back and forth, its entry triggers continuously untap both the Cauldron and Vohar, letting you endlessly loot through your deck while Carrion Feeder grows into a colossal threat.
