Viscera Seer + Faceless Butcher + Metamorphosis Fanatic

Viscera Seer

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 Viscera Seer 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 Viscera Seer ability.
8. Repeat from step 3.

This elegant loop is fueled by an endless cycle of entering and leaving the battlefield between Faceless Butcher and Metamorphosis Fanatic, where each creature constantly resurrects the other in a perpetual state of reincarnation. Whenever Faceless Butcher enters to exile Metamorphosis Fanatic, you simply sacrifice the Butcher to Viscera Seer to release the Fanatic from exile. That departure triggers Metamorphosis Fanatic to pull the Butcher right back out of your graveyard, letting you repeat the cycle indefinitely. With Viscera Seer sitting safely on the board to convert this violent recursion into infinite scrys, you gain a bottomless well of sacrifice and death triggers to sculpt your deck however you see fit.
