Cavalier of Night + Phantasmal Image + Carrion Feeder

Cavalier of Night

Phantasmal Image

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Phantasmal Image.
2. When Phantasmal Image dies, its last ability from Cavalier of Night triggers, returning itself from your graveyard to the battlefield as a copy of Cavalier of Night.
3. When Phantasmal Image enters the battlefield, its first triggered ability from Cavalier of Night triggers; choose not to sacrifice a creature.
4. Resolve the Carrion Feeder ability from step 1.
5. Repeat.

This clever loop relies on Phantasmal Image entering the battlefield as a copy of Cavalier of Night, whose mana value of 5 conveniently exceeds the copy restriction but allows the original Cavalier of Night's death trigger to fish the Image right back out of the graveyard. Once the copy hits the board, Carrion Feeder acts as the designated executioner to instantly sacrifice the Phantasmal Image, sending it back to the graveyard to trigger the recursion loop all over again. By repeating this cycle, you continuously feed Carrion Feeder for infinite +1/+1 counters while generating an endless stream of sacrifice, death, and entry triggers.
