Remembrance + Mortuary + Crimson Kobolds + Carrion Feeder

Remembrance

Mortuary

Crimson Kobolds

Carrion Feeder

How it works

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

This clever loop is centered around the zero-mana cost of Crimson Kobolds, allowing you to repeatedly sacrifice it to Carrion Feeder to pump up your primary threat with endless +1/+1 counters. The true brilliance of the engine lies in how Mortuary and Remembrance intercept the little creature's death simultaneously: Mortuary sends the Kobolds straight back to the top of your library, while Remembrance lets you tutor a copy right into your hand. This ensures that every time you cast the Crimson Kobolds for free, you immediately have another ready to feed to Carrion Feeder and repeat the cycle.
