Teshar, Ancestor's Apostle returns Scrap Trawler each time Sol Ring is cast; Scrap Trawler's death trigger then recurs Sol Ring when it's sacrificed to Umbral Collar Zealot, closing the loop. Every pass through adds colorless from Sol Ring's tap activation and a surveil from Umbral Collar Zealot, making this a recursive engine that both digs and generates mana simultaneously — the exact shell Teshar artifact decks are built around.

Variations

Cheaper, tighter, alternate lines

Any mana value 0 artifact that Scrap Trawler can return on Sol Ring's exit widens redundancy; Tormod's Crypt and Mishra's Bauble fill that slot if the bin runs light. Convert the infinite colorless into a win with Walking Ballista or Aetherflux Reservoir — the loop is the engine, not the kill.
