Mikaeus, the Unhallowed + Shilgengar, Sire of Famine + Pith Driller

Mikaeus, the Unhallowed

Shilgengar, Sire of Famine

Pith Driller

How it works

1. Activate Shilgengar by sacrifiicing Pith Driller.
2. When Pith Driller dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Pith Driller enters the battlefield, it triggers, putting a -1/-1 counter on it.
4. Resolve the Shilgengar ability.
5. Repeat.

This clever loop relies on Mikaeus, the Unhallowed to grant undying to our non-Human creatures, turning every trip to the graveyard into a return ticket. When Shilgengar, Sire of Famine feasts on Pith Driller as a sacrifice, Pith Driller's undying triggers to bring it right back with a +1/+1 counter. That resurrection immediately triggers Pith Driller's own entry ability, placing a -1/-1 counter on itself; state-based actions then cause the +1/+1 and -1/-1 counters to annihilate one another, leaving the Driller completely clean and ready to be sacrificed all over again.
