Altar of Dementia + Wormfang Drake + Metamorphosis Fanatic

Altar of Dementia

Wormfang Drake

Metamorphosis Fanatic

How it works

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

This elegant loop hinges on a recursive exchange between Wormfang Drake and Metamorphosis Fanatic, fueled by the relentless sacrifice engine of Altar of Dementia. When Wormfang Drake enters the battlefield and exiles Metamorphosis Fanatic, you immediately sacrifice the Drake to the Altar to mill an opponent. That sacrifice causes Wormfang Drake to leave the battlefield, triggering its ability to return Metamorphosis Fanatic, whose own entry trigger then plucks the Drake right back out of your graveyard. By repeating this cycle, you continuously generate death and sacrifice triggers to endlessly mill your opponents' libraries.
