Mortuary + Ravenous Intruder + Shield Sphere + Gwenom, Remorseless

Mortuary

Ravenous Intruder

Shield Sphere

Gwenom, Remorseless

How it works

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

This ingenious loop relies on turning a zero-cost artifact into an infinite engine, fueled entirely by the grim recycling power of Mortuary. By repeatedly feeding Shield Sphere to Ravenous Intruder, you trigger Mortuary's static ability to instantly place the sphere back on top of your library instead of letting it rest in the graveyard. Meanwhile, Gwenom, Remorseless grants you the crucial permission to cast that very same top card directly from your library, circumventing its mana cost entirely by paying zero life. The result is a relentless cascade of sacrifices that pumps Ravenous Intruder to astronomical proportions while racking up infinite triggers for your death and storm counts.
