Faceless Butcher + Metamorphosis Fanatic + Phantom Train

Faceless Butcher

Metamorphosis Fanatic

Phantom Train

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 Phantom Train 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 Phantom Train ability.
8. Repeat from step 3.

This clever loop relies on a classic oblivion-ring style cycle, where Metamorphosis Fanatic and Faceless Butcher continuously trade places between the battlefield, exile, and your graveyard. When Metamorphosis Fanatic enters the battlefield, its triggered ability pulls Faceless Butcher right back out of the graveyard to restart the exile chain. Meanwhile, Phantom Train acts as the engine's sacrifice outlet, letting you leverage the loop's infinite cycle to pump it with endless +1/+1 counters while triggering infinite deaths and leaves-the-battlefield effects.
