Mortuary + Carrion Feeder + Crookshank Kobolds + Gwenom, Remorseless

Mortuary

Carrion Feeder

Crookshank Kobolds

Gwenom, Remorseless

How it works

1. Activate Carrion Feeder by sacrificing Crookshank Kobolds
2. When Crookshank Kobolds dies, Mortuary triggers, putting Crookshank Kobolds from your graveyard onto the top of your library.
3. Resolve the Carrion Feeder ability.
4. Cast Crookshank Kobolds from the top of your library by paying 0 life.
5. Repeat.

This clever loop transforms free sacrifice outlets and zero-mana creatures into an infinite engine, supercharged by Gwenom, Remorseless to let you play right off the top of your library. By sacrificing Crookshank Kobolds to Carrion Feeder, Mortuary steps in to immediately rescue the tiny creature from the graveyard and place it right back on top of your library. From there, Gwenom, Remorseless allows you to recast the Kobolds for zero mana (paying life equal to its mana value, which is zero), feeding the cycle endlessly and stacking up infinite +1/+1 counters on Carrion Feeder.
