Remembrance + Mortuary + Blasting Station + Shield Sphere

Remembrance

Mortuary

Blasting Station

Shield Sphere

How it works

1. Activate Blasting Station by tapping it and sacrificing Shield Sphere.
2. When Shield Sphere dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Shield Sphere from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Shield Sphere and putting it into your hand.
5. Resolve the Blasting Station ability, dealing 1 damage to any target.
6. Cast Shield Sphere by paying 0.
7. When Shield Sphere enters the battlefield, Blasting Station triggers, untapping Blasting Station.
8. Repeat.

This clever loop turns the free-casting artifact Shield Sphere into an infinite source of destruction by orchestrating its perpetual cycle between the battlefield, graveyard, and hand. When you sacrifice the zero-mana defender to Blasting Station, Mortuary instantly intercepts it to place the card safely back on top of your library, while Remembrance simultaneously lets you tutor another copy straight to your hand—though since Mortuary already put the original there, you're simply setting up an infinite supply of free re-casts. Every single time Shield Sphere re-enters the battlefield, Blasting Station's triggered ability untaps the launcher, allowing you to repeat the firing process endlessly until your opponents are reduced to ash.
