Mortuary + Bile Urchin + Susurian Voidborn + Gwenom, Remorseless

Mortuary

Bile Urchin

Susurian Voidborn

Gwenom, Remorseless

How it works

1. Activate Bile Urchin by sacrificing it.
2. When Bile Urchin dies, Mortuary and Susurian Voidborn trigger.
3. Resolve the Mortuary trigger, putting Bile Urchin from your graveyard onto the top of your library.
4. Resolve the Susurian Voidborn trigger, causing you to gain 1 life and target opponent to lose 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 turns a modest spirit into a relentless engine of attrition by chaining death triggers into immediate recursive card advantage. You begin by sacrificing Bile Urchin, which triggers its own drain effect alongside Susurian Voidborn while Mortuary quietly intercepts the creature as it hits the graveyard to place it directly back on top of your library. From there, Gwenom, Remorseless steps in to let you cast spells from the top of your library, trading life for mana so you can replay the Urchin without breaking a sweat. Susurian Voidborn ensures every iteration drains your opponent while padding your life total to comfortably sustain Gwenom, Remorseless and its alternative payment cost.
