Mortuary + Carrion Feeder + Kobolds of Kher Keep + Gwenom, Remorseless

Mortuary

Carrion Feeder

Kobolds of Kher Keep

Gwenom, Remorseless

How it works

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

This clever loop turns zero-mana creatures into an infinite engine by leveraging Mortuary to recycle casualties straight back to the top of your library every time they hit the graveyard. Carrion Feeder acts as the sacrifice outlet that continuously triggers this recycling while growing larger with every iteration. Because Kobolds of Kher Keep costs zero mana to cast, it can be replayed instantly without needing any actual resources, feeding right back into the sacrifice loop. Meanwhile, Gwenom, Remorseless provides the alternate casting permission and life-payment option needed to play those recycled cards directly off the top of your library, making the entire engine self-sustaining.
