Teshar, Ancestor's Apostle + Salvager of Ruin + Woe Strider + Shield Sphere

Teshar, Ancestor's Apostle

Salvager of Ruin

Woe Strider

Shield Sphere

How it works

1. Activate Woe Strider by sacrificing Shield Sphere.
2. Activate Salvager of Ruin by sacrificing it, returning Shield Sphere from your graveyard to your hand.
3. Cast Shield Sphere by paying 0.
4. Teshar triggers, returning Salvager of Ruin from your graveyard to the battlefield.
5. Repeat.

This loop turns free sacrifices into an endless engine by pairing Woe Strider's ability to swallow a creature with Salvager of Ruin's power to recur that exact sacrificed permanent. By feeding the zero-mana Shield Sphere to the altar, you fuel Salvager of Ruin so it can pull the sphere right back to your hand for another deployment. Casting that free artifact acts as a historic spell that triggers Teshar, Ancestor's Apostle, immediately pulling Salvager of Ruin back from the graveyard to the battlefield to reset the cycle.
