Blightbeetle + Blasting Station + Wrong Turn

Blightbeetle

Blasting Station

Wrong Turn

How it works

1. Donate Blightbeetle to an opponent
2. Activate Blasting Station by tapping it and 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. When the undying creature enters, Blasting Station triggers, untapping Blasting Station.
5. Resolve the Blasting Station ability from step 2.
6. Repeat from step 2.

This clever loop turns an opponent's own defenses against them by utilizing Wrong Turn to hand over Blightbeetle, locking down their ability to receive +1/+1 counters. With that restriction in place, your chosen undying creature can continually sacrifice itself to Blasting Station without ever accumulating the counters that would normally permanently lock it out of the graveyard loop. Every time the creature leaves the graveyard and returns, Blasting Station's triggered ability untaps the artifact so you can repeat the sacrifice, converting the endless cycle of death and rebirth into infinite damage.
