Mortuary + Vindictive Vampire + Bile Urchin + Gwenom, Remorseless

Mortuary

Vindictive Vampire

Bile Urchin

Gwenom, Remorseless

How it works

1. Activate Bile Urchin by sacrificing it.
2. When Bile Urchin dies, Mortuary and Vindictive Vampire trigger.
3. Resolve the Mortuary trigger, putting Bile Urchin from your graveyard onto the top of your library.
4. Resolve the Vindictive Vampire trigger, dealing 1 damage to each opponent and causing you to gain 1 life.
5. Resolve the Bile Urchin ability.
6. Cast Bile Urchin from the top of your library by paying 1 life.
7. Repeat.

This clever loop harnesses Gwenom, Remorseless to turn the top of your library into a hidden hand, allowing you to bypass mana costs by paying life instead. By sacrificing Bile Urchin to drain an opponent, you set off a cascade where Mortuary neatly catches the creature and recycles it directly to the top of your library, ready for Gwenom to cast it again. Meanwhile, Vindictive Vampire quietly watches the carnage, translating every single death into recurring life gain and unyielding damage to seal the victory.
