Mortuary + Vein Ripper + Bile Urchin + Gwenom, Remorseless

Mortuary

Vein Ripper

Bile Urchin

Gwenom, Remorseless

How it works

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

This ingenious loop turns a humble Bile Urchin into an endless engine of doom, fueled by Mortuary's ability to seamlessly recycle any creature that hits the graveyard directly back onto your library. Meanwhile, Vein Ripper amplifies every single one of those deaths to rapidly drain your opponents dry while padding your own life total. Gwenom, Remorseless provides the crucial permission to cast that same Bile Urchin directly off the top of your library repeatedly, neatly bypassing traditional mana costs at the modest expense of your life total—a cost easily offset by Vein Ripper's steady stream of lifegain.
