Mortuary + Shilgengar, Sire of Famine + Phyrexian Walker + Gwenom, Remorseless

Mortuary

Shilgengar, Sire of Famine

Phyrexian Walker

Gwenom, Remorseless

How it works

1. Activate Shilgengar 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 Shilgengar ability.
4. Cast Phyrexian Walker from the top of your library by paying 0 life.
5. Repeat.

This loop transforms a humble artifact creature into an endless engine by leveraging the passive protection of Mortuary, which catches your sacrifices and quietly returns them straight to the top of your library. Shilgengar, Sire of Famine acts as the catalyst by turning that sacrifice into Blood tokens while you feed it Phyrexian Walker for free. Meanwhile, Gwenom, Remorseless grants you the crucial top-deck casting permission, allowing you to bypass mana costs entirely and replay the Walker directly from your library by paying life instead—enabling an unstoppable cycle of death and rebirth.
