Mortuary + Viscera Seer + Shield Sphere + Gwenom, Remorseless

Mortuary

Viscera Seer

Shield Sphere

Gwenom, Remorseless

How it works

1. Activate Viscera Seer 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 Viscera Seer ability.
4. Cast Shield Sphere from the top of your library by paying 0 life.
5. Repeat.

This clever loop uses Mortuary as the engine to ensure that whenever a creature hits your graveyard, it immediately returns to the top of your library instead of staying there. By utilizing Viscera Seer, you have a free, repeatable sacrifice outlet that also lets you scry along the way. Shield Sphere acts as the ultimate zero-mana fuel for this sacrifice loop, requiring no resources to replay. Finally, Gwenom, Remorseless enables you to cast that Shield Sphere straight off the top of your library for zero life—thanks to its alternative mana payment—completing a seamless cycle that endlessly repeats its steps.
