Metamorphosis Fanatic + Body Double + Bartolomé del Presidio

Metamorphosis Fanatic

Body Double

Bartolomé del Presidio

How it works

1. Cast Metamorphosis Fanatic by paying 4.
2. When Metamorphosis Fanatic enters the battlefield, it triggers, targeting Body Double.
3. Holding priority, activate Bartolomé del Presidio by sacrificing Metamorphosis Fanatic, putting a +1/+1 counter on Bartolomé del Presidio.
4. Resolve the Metamorphosis Fanatic ability, returning Body Double from your graveyard to the battlefield as a copy of Metamorphosis Fanatic.
5. When Body Double enters the battlefield, it triggers, targeting Metamorphosis Fanatic.
6. Holding priority, activate Bartolomé del Presidio by sacrificing Body Double, putting a +1/+1 counter on Bartolomé del Presidio.
7. Resolve the Body Double ability, returning Metamorphosis Fanatic from your graveyard to the battlefield.
8. Repeat from step 2.

This loop creates a perpetual cycle of resurrection by leveraging the clever overlapping triggers of Metamorphosis Fanatic and Body Double. Whenever one enters the battlefield, its ability targets the other waiting in the graveyard, allowing Body Double to enter as a fresh copy of Metamorphosis Fanatic and restart the entire chain. Bartolomé del Presidio acts as the essential executioner for this loop, letting you sacrifice the active creature at instant speed to fuel endless death triggers, leave-the-battlefield triggers, and accumulate an arbitrarily large number of +1/+1 counters.
