Teshar, Ancestor's Apostle + Scrap Trawler + Bloodflow Connoisseur + Dark Sphere

Teshar, Ancestor's Apostle

Scrap Trawler

Bloodflow Connoisseur

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

This ingenious loop uses Teshar, Ancestor's Apostle as your engine, transforming every historic spell you cast into a resurrection mechanic that pulls Scrap Trawler straight out of the graveyard. While Scrap Trawler is on the board, sacrificing Dark Sphere to the maw of Bloodflow Connoisseur triggers the Trawler's ability to recycle that very same Dark Sphere right back to your hand. Because Dark Sphere costs zero mana to recast, playing it again triggers Teshar anew, allowing you to endlessly loop the sphere and the Trawler to fuel Bloodflow Connoisseur's hunger for infinite growth and sacrifice triggers.
