Blightbeetle + Shilgengar, Sire of Famine + Stiltzkin, Moogle Merchant

Blightbeetle

Shilgengar, Sire of Famine

Stiltzkin, Moogle Merchant

How it works

1. Donate Blightbeetle to an opponent
2. Activate Shilgengar 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 Shilgengar ability.
5. Repeat from step 2.

This wicked loop hinges on Blightbeetle's passive ability, which prevents your opponents' creatures from ever acquiring +1/+1 counters. By using Stiltzkin, Moogle Merchant to donate that very Blightbeetle across the table, you ensure that any creature you control with undying will safely negate its usual counter penalty upon resurrection. With the stage set, Shilgengar, Sire of Famine acts as your engine, letting you continually sacrifice those persistent creatures to generate a steady stream of Blood tokens and death triggers without ever running out of fresh fodder.
