Mortuary + Altar of Dementia + Bontu's Monument + Gwenom, Remorseless

Mortuary

Altar of Dementia

Bontu's Monument

Gwenom, Remorseless

How it works

1. Activate Altar of Dementia 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 Altar of Dementia 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 turning your library into a recycling bin for low-cost threats, orchestrated by Altar of Dementia to mill your opponents out card by card. Whenever you sacrifice your creature, Mortuary steps in to instantly place it right back on top of your library where it can be played again. Gwenom, Remorseless grants you the vital permission to cast that creature straight from the top of your library while paying life instead of its mana cost. Meanwhile, Bontu's Monument quietly offsets that life payment by draining your opponents and gaining you life with every single re-cast, turning a closed-loop execution into an overwhelming victory.
