Mortuary + Blood Pet + Embalmed Ascendant + Gwenom, Remorseless

Mortuary

Blood Pet

Embalmed Ascendant

Gwenom, Remorseless

How it works

1. Activate Blood Pet by sacrificing it.
2. When Blood Pet dies, Mortuary and Embalmed Ascendant trigger.
3. Resolve the Mortuary trigger, putting Blood Pet from your graveyard onto the top of your library.
4. Resolve the Embalmed Ascendant trigger, causing you to gain 1 life and each opponent to lose 1 life.
5. Cast Blood Pet from the top of your library by paying 1 life.
6. Repeat.

This elegant loop turns a humble mana-producer into a recursive engine by pairing Mortuary with the life-manipulation of Embalmed Ascendant. When you sacrifice Blood Pet for black mana, Mortuary catches it on the way to the graveyard and neatly stacks it right back on top of your library. Meanwhile, Embalmed Ascendant ensures that each death drains your opponents and pads your life total, which directly fuels Gwenom, Remorseless. Gwenom's attack-triggered ability lets you bypass mana costs entirely by paying life instead, allowing you to replay Blood Pet endlessly from the top of your library for infinite sacrifices, triggers, and black mana.
