Teshar, Ancestor's Apostle + Scrap Trawler + Dark Sphere + Phantom Train

Teshar, Ancestor's Apostle

Scrap Trawler

Dark Sphere

Phantom Train

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

This clever loop turns cheap artifact sacrifice into an engine fueled by Teshar, Ancestor's Apostle, which continuously plucks Scrap Trawler out of the graveyard whenever you cast a historic spell like Dark Sphere. Once Scrap Trawler is back on the battlefield, it leverages its death trigger to return the sacrificed Dark Sphere straight to your hand, ready to be cast all over again. Meanwhile, Phantom Train serves as the necessary outlet to sacrifice the Trawler, feeding the cycle while growing larger with every iteration.
