Mortuary + Shield Sphere + Phantom Train + Gwenom, Remorseless

Mortuary

Shield Sphere

Phantom Train

Gwenom, Remorseless

How it works

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

This ingenious loop transforms a seemingly harmless wall into an engine of endless power by exploiting the interaction between the top of your library and the graveyard. With Gwenom, Remorseless in play attacking to unlock the top of your library, you can repeatedly cast Shield Sphere for zero life, completely bypassing traditional mana costs. Each time you sacrifice the Shield Sphere to Phantom Train—which simultaneously pumps the Vehicle and animates it—Mortuary instantly catches the zero-cost artifact in your graveyard and tucks it right back onto the top of your library. This creates a perpetual cycle that grows Phantom Train to infinite size while generating an unlimited storm count and endless sacrifice triggers.
