Blightbeetle + Umbral Collar Zealot + Blim, Comedic Genius

Blightbeetle

Umbral Collar Zealot

Blim, Comedic Genius

How it works

1. Donate Blightbeetle to an opponent
2. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability.
5. Repeat from step 2.

This delightfully twisted loop uses Blim, Comedic Genius to donate Blightbeetle across the table, turning your opponent's side of the board into a hostile environment where +1/+1 counters simply cannot exist. With that static prevention in place, you can feed an undying creature repeatedly to Umbral Collar Zealot without worrying about the usual counters that would normally shut down the recursion. Because Blightbeetle stops those counters from sticking, the undying trigger brings the creature right back endlessly, fueling infinite sacrifices, death triggers, and surveil sculpting via Umbral Collar Zealot's activation.
