Mortuary + Extruder + Shield Sphere + Gwenom, Remorseless

Mortuary

Extruder

Shield Sphere

Gwenom, Remorseless

How it works

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

This clever loop turns zero-mana artifacts into a perpetual engine by pairing Extruder's artifact sacrifice outlet with Mortuary's clever trigger that returns creatures straight to the top of your library upon dying. Shield Sphere is the perfect fuel for this cycle, offering up a free sacrifice target that immediately puts itself back in position to be recast. The true genius of the build unlocks once Gwenom, Remorseless joins the board, letting you bypass mana costs entirely and cast that same Shield Sphere straight from the top of your library for zero life. As you endlessly cycle the Sphere through the graveyard and back, Extruder dishes out an endless stream of +1/+1 counters to grow your team to staggering proportions while racking up infinite storm and death triggers.
