Blightbeetle + Viscera Seer + Blim, Comedic Genius

Blightbeetle

Viscera Seer

Blim, Comedic Genius

How it works

1. Donate Blightbeetle to an opponent
2. Activate Viscera Seer by sacrificing the undying creature.
3. When the undying creature dies, its undying ability triggers, returning itself from your graveyard to the battlefield without a +1/+1 counter on it due to Blightbeetle.
4. Resolve the Viscera Seer ability.
5. Repeat from step 2.

This clever loop relies on a subtle interaction with Blightbeetle, whose static ability prevents opponents' creatures from receiving +1/+1 counters. By first donating Blightbeetle to your opponent using Blim, Comedic Genius—whose combat damage trigger forces them to take control of it—you completely suppress the counter-placement side of an undying creature's return. With the safety net of Blightbeetle on the opposing side, you can repeatedly sacrifice your undying creature to Viscera Seer, letting it slip right back to the battlefield with no counter to stop it and generating an endless loop of sacrifices, death triggers, and scry 1s.
