Vohar, Vodalian Desecrator

Haunted One

Cauldron of Souls

Deceiver Exarch

Blasting Station

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 Blasting Station by tapping it and 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 and Blasting Station trigger.
7. Resolve the Blasting Station trigger, untapping it.
8. Resolve the Deceiver Exarch trigger, untapping Cauldron of Souls.
9. Resolve the Blasting Station ability from step 4, dealing 1 damage to any target.
10. Activate Cauldron of Souls by tapping it, giving Deceiver Exarch persist until end of turn.
11. Activate Blasting Station by tapping it and sacrificing Deceiver Exarch.
12. When Deceiver Exarch dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
13. When Deceiver Exarch enters the battlefield, it and Blasting Station trigger.
14. Resolve the Blasting Station trigger, untapping it.
15. Resolve the Deceiver Exarch trigger, untapping Vohar.
16. Resolve the Blasting Station ability from step 9, dealing 1 damage to any target.
17. Repeat.

This clever loop turns the stat-boosting static ability of Haunted One into an engine for infinite damage by exploiting the delicate math between +1/+1 and -1/-1 counters. You begin by tapping Vohar, Vodalian Desecrator to cycle through your deck, which simultaneously grants your shared creature types undying thanks to Haunted One's passive buff. Sacrificing Deceiver Exarch to Blasting Station sends it to the graveyard, where undying brings it right back; its entry triggers then untap Blasting Station to let you ping your opponents, while also untapping Cauldron of Souls. You can then use Cauldron of Souls to grant Deceiver Exarch persist, allowing you to sacrifice it again so that persist brings it back with a -1/-1 counter—which neatly cancels out the previous +1/+1 counter and sets you up to loop the entire process indefinitely.
