Remembrance + Mortuary + Woe Strider + Shield Sphere

Remembrance

Mortuary

Woe Strider

Shield Sphere

How it works

1. Activate Woe Strider by 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 Woe Strider ability, causing you to scry 1.
6. Cast Shield Sphere by paying 0.
7. Repeat.

This loop transforms the humble, free-blocking Shield Sphere into an endless engine of sacrifice and recursion, fueled entirely by Woe Strider's ability to devour it at will. Whenever the Sphere hits the graveyard, Mortuary quietly catches it and places it right back on top of your library, while Remembrance exploits that exact death to tutor another copy straight to your hand for zero mana. Because the Sphere costs nothing to recast, you can repeat this sequence indefinitely to churn through your deck with infinite scry triggers, stack an astronomical storm count, or trigger any other death- and sacrifice-based abilities you might need to win the game.
