Teshar, Ancestor's Apostle + Scrap Trawler + Lion's Eye Diamond + Carrion Feeder

Teshar, Ancestor's Apostle

Scrap Trawler

Lion's Eye Diamond

Carrion Feeder

How it works

1. Cast Lion's Eye Diamond by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Lion's Eye Diamond by discarding your hand and sacrificing it.
4. Activate Carrion Feeder by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Lion's Eye Diamond from your graveyard to your hand.
6. Resolve the Carrion Feeder ability.
7. Repeat.

This elegant loop uses Teshar, Ancestor's Apostle as the engine, turning every iteration of casting a historic spell into a recursive resurrection for Scrap Trawler. By sacrificing Lion's Eye Diamond to its own mana ability and discarding your hand, you fuel the sequence while putting the Diamond into the graveyard where Scrap Trawler’s artifact-retrieval trigger can bounce it straight back to your hand. Meanwhile, Carrion Feeder acts as the designated executioner, giving you a reliable outlet to sacrifice Scrap Trawler and grow its own power while triggering the entire cycle anew.
