Blightbeetle + Umbral Collar Zealot + Wrong Turn

Blightbeetle

Umbral Collar Zealot

Wrong Turn

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.

By casting Wrong Turn, you hand your opponent control of Blightbeetle, locking down their board so that creatures can never receive +1/+1 counters. With that restriction in place, you can feed any creature with undying into Umbral Collar Zealot over and over again. Because Blightbeetle prevents the usual +1/+1 counter from being placed on the dying creature as it returns, its undying ability triggers indefinitely upon each sacrifice. This creates an endless loop of deaths, entries, and surveil triggers that fuels your entire strategy.
