Bartolomé del Presidio + Faceless Butcher + Metamorphosis Fanatic

Bartolomé del Presidio

Faceless Butcher

Metamorphosis Fanatic

How it works

1. Cast Faceless Butcher by paying its mana cost.
2. When Faceless Butcher enters, its first ability triggers, exiling Metamorphosis Fanatic.
3. Activate Bartolomé del Presidio by sacrificing Faceless Butcher.
4. When Faceless Butcher dies, its second ability triggers, returning Metamorphosis Fanatic from exile to the battlefield.
5. When Metamorphosis Fanatic enters, it triggers, returning Faceless Butcher from your graveyard to the battlefield.
6. When Faceless Butcher enters, its first ability triggers, exiling Metamorphosis Fanatic.
7. Resolve the Bartolomé del Presidio ability.
8. Repeat from step 3.

This infinite loop creates a self-sustaining cycle of life and death, anchored by the sacrifice outlet Bartolomé del Presidio to constantly pump up its own power with +1/+1 counters. The engine relies on the interplay between Faceless Butcher and Metamorphosis Fanatic: when the Butcher enters to exile the Fanatic, sacrificing the Butcher immediately frees the Fanatic to return to the battlefield. In turn, the Fanatic's entry trigger brings the Butcher right back from the graveyard, restarting the cycle and generating an infinite storm of enters-the-battlefield, leaves-the-battlefield, and death triggers.
