Teshar, Ancestor's Apostle + Scrap Trawler + Arcbound Ravager + Dark Sphere

Teshar, Ancestor's Apostle

Scrap Trawler

Arcbound Ravager

Dark Sphere

How it works

1. Cast Dark Sphere by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Dark Sphere by tapping and sacrificing it.
4. Activate Arcbound Ravager by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Dark Sphere from your graveyard to your hand.
6. Resolve the Arcbound Ravager ability.
7. Repeat.

This recursive loop uses Teshar, Ancestor's Apostle as the engine, turning every recast of a cheap artifact into a resurrection machine for your graveyard. By casting Dark Sphere, you trigger Teshar to bring back Scrap Trawler, which acts as the crucial glue that allows your artifacts to recycle themselves. When you sacrifice Dark Sphere to Arcbound Ravager, Scrap Trawler's ability triggers to bounce Dark Sphere right back to your hand. You can then replay it to repeat the entire process indefinitely, fueled by Arcbound Ravager's ability to effortlessly bin your artifacts while growing massive with infinite +1/+1 counters.
