Remembrance + Mortuary + Carrion Feeder + Crookshank Kobolds

Remembrance

Mortuary

Carrion Feeder

Crookshank Kobolds

How it works

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

This clever loop turns zero-mana fodder into endless growth by manipulating where dead creatures go. When you feed Crookshank Kobolds to Carrion Feeder, both Mortuary and Remembrance trigger simultaneously; Mortuary places the Kobolds back on top of your library while Remembrance lets you tutor another copy straight into your hand. Because the Kobolds cost nothing to cast, you can immediately replay them from your hand to repeat the cycle, feeding Carrion Feeder an infinite supply of sacrifices to pump it up to astronomical sizes.
