Mortuary + Bartolomé del Presidio + Serrated Scorpion + Gwenom, Remorseless

Mortuary

Bartolomé del Presidio

Serrated Scorpion

Gwenom, Remorseless

How it works

1. Activate Bartolomé del Presidio by sacrificing Serrated Scorpion.
2. When Serrated Scorpion dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Serrated Scorpion from your graveyard onto the top of your library.
4. Resolve the Serrated Scorpion trigger, causing you to gain 2 life and dealing 2 damage to each opponent.
5. Resolve the Bartolomé del Presidio ability.
6. Cast Serrated Scorpion from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This clever loop turns your graveyard into a revolving door for life-drain. Bartolomé del Presidio serves as the sacrificial outlet, sending Serrated Scorpion to the graveyard where its death triggers drain your opponents while Mortuary immediately recycles the Scorpion back onto the top of your library. That's where Gwenom, Remorseless steps in, allowing you to bypass mana costs and recast the Scorpion directly from the library by paying life instead—an expenditure more than cushioned by the Scorpion's own lifegain.
