Mikaeus, the Unhallowed + Otherworldly Escort + Bartolomé del Presidio

Mikaeus, the Unhallowed

Otherworldly Escort

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio by sacrificing Otherworldly Escort.
2. When Otherworldly Escort dies, it triggers, returning itself from your graveyard to the battlefield as a Spirit Detective.
3. Resolve the Bartolomé del Presidio ability.
4. Activate Bartolomé del Presidio by sacrificing Otherworldly Escort.
5. When Otherworldly Escort dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
6. Resolve the Bartolomé del Presidio ability.
7. Repeat.

This clever loop hinges on the clever interaction between Otherworldly Escort's unique resurrection trigger and Mikaeus, the Unhallowed's static undying anthem. When you sacrifice Otherworldly Escort to Bartolomé del Presidio the first time, its own death trigger returns it as a non-Human Spirit Detective, wiping away any counters. Once it dies a second time, Mikaeus, the Unhallowed steps in to grant it undying, bringing it back with a +1/+1 counter so the process can continuously cycle between these two distinct resurrection triggers. Because Bartolomé del Presidio acts as a repeatable sacrifice outlet that also grows larger with each iteration, this engine churns out infinite sacrifice, death, and entry triggers while endlessly pumping up your board.
