Mortuary + Ravenous Intruder + Phyrexian Walker + Gwenom, Remorseless

Mortuary

Ravenous Intruder

Phyrexian Walker

Gwenom, Remorseless

How it works

1. Activate Ravenous Intruder by sacrificing Phyrexian Walker
2. When Phyrexian Walker dies, Mortuary triggers, putting Phyrexian Walker from your graveyard onto the top of your library.
3. Resolve the Ravenous Intruder ability.
4. Cast Phyrexian Walker from the top of your library by paying 0 life.
5. Repeat.

This clever loop hinges on Mortuary, which acts as the ultimate recycling bin by tucking any creature that dies straight back onto the top of your library. Ravenous Intruder provides the necessary outlet by consuming artifacts, allowing you to seamlessly sacrifice Phyrexian Walker for a growing power boost. Meanwhile, Gwenom, Remorseless grants you the vital permission to cast spells directly from the top of your library while bypassing traditional mana costs in exchange for life. Since Phyrexian Walker costs zero mana to begin with, you can cast it repeatedly for free off the top of your library to endlessly fuel the Intruder and rack up massive triggers.
