Teshar, Ancestor's Apostle + Scrap Trawler + Altar of Dementia + Dark Sphere

Teshar, Ancestor's Apostle

Scrap Trawler

Altar of Dementia

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 Altar of Dementia by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Dark Sphere from your graveyard to your hand.
6. Resolve the Altar of Dementia ability.
7. Repeat.

This cunning little loop turns a humble zero-mana artifact into an unstoppable engine of endless repetition. By casting Dark Sphere, you feed a historic spell directly into Teshar, Ancestor's Apostle to constantly resurrect Scrap Trawler from the graveyard. Once Scrap Trawler is on the battlefield, sacrificing it to Altar of Dementia triggers its ability to pluck Dark Sphere right back out of the graveyard and return it to your hand, ready to be recast. Dark Sphere acts as the ultimate low-cost enabler for this recursion, letting you endlessly mill your opponents and generate an infinite storm count while leveraging Scrap Trawler and Teshar, Ancestor's Apostle to keep the loop spinning forever.
