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

Teshar, Ancestor's Apostle

Scrap Trawler

Lion's Eye Diamond

Atog

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 Atog 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 Atog ability.
7. Repeat.

This loop is a masterclass in recursive recycling, using Teshar, Ancestor's Apostle as your engine to constantly pull Scrap Trawler back from the graveyard whenever you cast a historic spell. The real trick to fueling this loop comes from Lion's Eye Diamond, which gives you the mana needed to keep going by sacrificing itself, only for Scrap Trawler's death trigger to hand the Diamond right back to your hand with its ability to return cheaper artifacts. Meanwhile, Atog acts as the reliable executioner in the corner, providing a sacrifice outlet to send Scrap Trawler to the graveyard so the whole process can spin endlessly.
