Blightbeetle + Thermopod + Blim, Comedic Genius

Blightbeetle

Thermopod

Blim, Comedic Genius

How it works

1. Donate Blightbeetle to an opponent
2. Activate Thermopod 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. Repeat from step 2.

This clever loop relies on a creature with undying dying and returning to the battlefield repeatedly, but with a clever twist: Blightbeetle ensures that your opponents' creatures can't have +1/+1 counters placed on them, neutralizing the restriction that normally stops undying from triggering a second time. By using Thermopod as a reliable sacrifice outlet, you turn that endless cycle of resurrection into an infinite stream of red mana and death triggers. Finally, the chaotic presence of Blim, Comedic Genius looms over your board state, ready to leverage your control over permanents—or perhaps donate the very Blightbeetle that makes the loop possible to an opponent in the first place.
