Mikaeus, the Unhallowed + Morselhoarder + Thermopod

Mikaeus, the Unhallowed

Morselhoarder

Thermopod

How it works

1. Activate Thermopod by sacrificing Morselhoarder.
2. When Morselhoarder dies, its undying ability triggers, returning it from your graveyard to the battlefield without a +1/+1 counter on it due to its replacement effect.
3. Repeat.

This clever loop turns Morselhoarder into an endless mana engine by exploiting how counters interact with the battlefield. Because Mikaeus, the Unhallowed grants undying to non-Human creatures, every time Morselhoarder is sacrificed to Thermopod, it returns with a +1/+1 counter that immediately annihilates one of its inherent -1/-1 counters as a state-based action. This leaves the creature clean of counters and ready to be sacrificed over and over again, fueling Thermopod for infinite red mana while generating an endless storm of entry, death, and sacrifice triggers.
