Mortuary

Ashes of the Abhorrent

Phyrexian Dreadnought

Gwenom, Remorseless

How it works

1. Cast Phyrexian Dreadnought from the top of your library by paying 1 life.
2. When Phyrexian Dreadnought enters, it triggers, causing you to sacrifice it.
3. When Phyrexian Dreadnought dies, Mortuary and Ashes of the Abhorrent trigger.
4. Resolve the Mortuary trigger, putting Phyrexian Dreadnought from your graveyard onto the top of your library.
5. Resolve the Ashes of the Abhorrent trigger, causing you to gain 1 life
6. Repeat.

This clever engine transforms Gwenom, Remorseless into a lethal loop by leveraging its ability to cast creatures directly from the top of your library using life instead of mana. When you cast Phyrexian Dreadnought this way, its massive enter-the-battlefield trigger forces you to instantly sacrifice it, sending it straight to the graveyard. At that exact moment, Mortuary steps in to intercept the creature and place it right back on top of your library, perfectly setting up Gwenom to cast it again. Meanwhile, Ashes of the Abhorrent quietly pads your life total with every death trigger to help offset the life you're paying, creating a seamless, self-sustaining loop of endless sacrifices.
