Mortuary + Bartolomé del Presidio + Bontu's Monument + Gwenom, Remorseless

Mortuary

Bartolomé del Presidio

Bontu's Monument

Gwenom, Remorseless

How it works

1. Activate Bartolomé del Presidio by sacrificing a creature with mana value 1 or less.
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Resolve the Bartolomé del Presidio ability.
4. Cast the creature from the top of your library by paying 1 life.
5. Bontu's Monument triggers, causing you to gain 1 life and each opponent to lose 1 life.
6. Repeat.

This clever loop relies on Mortuary to intercept your sacrifices and instantly recycle them back to the top of your library every time a creature bites the dust. Once Gwenom, Remorseless is on the battlefield, her attack-triggered ability allows you to look at and play cards directly from that top spot, letting you pay life instead of mana to recast whatever Mortuary just put there. Meanwhile, Bartolomé del Presidio acts as the engine's sacrifice outlet—pumping up his own stats with every iteration—while Bontu's Monument provides the crucial payoff that drains your opponents out of the game while simultaneously offsetting the life you spent to recast your creature.
