Melira, Sylvok Outcast + Scuzzback Marauders + Carrion Feeder

Melira, Sylvok Outcast

Scuzzback Marauders

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Scuzzback Marauders.
2. When Scuzzback Marauders dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. Resolve the Carrion Feeder ability
4. Repeat.

This loop turns a simple sacrifice outlet into an engine of endless growth by exploiting the interaction between creature death and recursion. Whenever you sacrifice Scuzzback Marauders to Carrion Feeder, the Marauders's persist ability tries to bring it back with a -1/-1 counter, but Melira, Sylvok Outcast's static ability steps in to prevent those counters from ever being placed. Because the Marauders return completely clean, you can feed them back into Carrion Feeder over and over to generate infinite sacrifice triggers, death triggers, and a massively oversized Carrion Feeder.
