Mortuary + Extruder + Memnite + Gwenom, Remorseless

Mortuary

Extruder

Memnite

Gwenom, Remorseless

How it works

1. Activate Extruder by sacrificing Memnite
2. When Memnite dies, Mortuary triggers, putting Memnite from your graveyard onto the top of your library.
3. Resolve the Extruder ability.
4. Cast Memnite from the top of your library by paying 0 life.
5. Repeat.

This elegant loop is fueled by Extruder, which converts the ultimate expendable artifact—Memnite—into a permanent +1/+1 counter for your board while sending the little construct straight to the graveyard. The moment Memnite hits the bin, Mortuary catches it mid-flight and places it right back on top of your library, setting up the final piece of the puzzle. With Gwenom, Remorseless on the battlefield, you are granted permission to play cards directly from the top of your library while bypassing traditional mana costs in exchange for life; because Memnite costs zero, you pay zero life to recast it endlessly, fueling an infinite stream of triggers.
