Teshar, Ancestor's Apostle + Scrap Trawler + Lion's Eye Diamond + Grimgrin, Corpse-Born

Teshar, Ancestor's Apostle

Scrap Trawler

Lion's Eye Diamond

Grimgrin, Corpse-Born

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 tapping and sacrificing it.
4. Activate Grimgrin 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 Grimgrin ability.
7. Repeat.

This ingenious loop hinges on a clever recycling chain powered by Teshar, Ancestor's Apostle and Scrap Trawler working in tandem. By casting Lion's Eye Diamond, you trigger Teshar to pull Scrap Trawler back from the graveyard, while sacrificing the Diamond for mana simultaneously feeds its own return to your hand through Scrap Trawler's death trigger. Meanwhile, Grimgrin, Corpse-Born acts as the reliable sacrifice outlet that keeps the engine moving, letting you funnel your mana and resources into generating an infinite storm count and endless +1/+1 counters.
