Remembrance + Mortuary + Phyrexian Walker + Carrion Feeder

Remembrance

Mortuary

Phyrexian Walker

Carrion Feeder

How it works

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

This elegant loop turns a humble artifact creature into endless growth by leveraging graveyard and library manipulation in tandem. You begin by feeding Phyrexian Walker to Carrion Feeder, which immediately grows larger thanks to its sacrifice-pump ability. As the Walker hits the graveyard, Mortuary quietly repositions it to the top of your library while Remembrance simultaneously triggers to fetch another copy directly into your hand. Because Phyrexian Walker costs zero mana to cast, you can immediately replay it and repeat the cycle, generating an endless storm count along with infinite sacrifices, deaths, and enters-the-battlefield triggers.
