Melira, Sylvok Outcast + Viscera Seer + Lingering Tormentor

Melira, Sylvok Outcast

Viscera Seer

Lingering Tormentor

How it works

1. Activate Viscera Seer by sacrificing Lingering Tormentor.
2. When Lingering Tormentor dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. Resolve the Viscera Seer ability
4. Repeat.

This loop turns a simple sacrifice outlet into an endless engine by neutralizing the built-in drawback of the persist mechanic. While Viscera Seer provides a free way to bin creatures and manipulate your library, it is Melira, Sylvok Outcast's static ability that does the heavy lifting, stepping in to prevent the -1/-1 counters from ever being placed on your creatures. This allows Lingering Tormentor to repeatedly die and return from the graveyard ad infinitum, generating endless death triggers, sacrifice triggers, and scry 1s to sculpt your deck however you see fit.
