Remembrance + Mortuary + Carrion Feeder + Ornithopter

Remembrance

Mortuary

Carrion Feeder

Ornithopter

How it works

1. Activate Carrion Feeder by sacrificing Ornithopter.
2. When Ornithopter dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Ornithopter from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Ornithopter and putting it into your hand.
5. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
6. Cast Ornithopter by paying 0.
7. Repeat.

This loop transforms a humble zero-mana artifact into an engine of endless growth. You begin by using Carrion Feeder to snack on Ornithopter, which triggers both Mortuary and Remembrance simultaneously. Mortuary ensures the sacrificed Ornithopter returns neatly to the top of your library, while Remembrance lets you tutor a fresh copy straight to your hand—guaranteeing you never run out of ammo. Because Ornithopter costs nothing to recast, you can immediately replay it and feed it back to Carrion Feeder, piling up an infinite number of +1/+1 counters on the Feeder while generating boundless sacrifice, death, and trigger counts.
