Teshar, Ancestor's Apostle + Scrap Trawler + Krark-Clan Ironworks + Tormod's Crypt

Teshar, Ancestor's Apostle

Scrap Trawler

Krark-Clan Ironworks

Tormod's Crypt

How it works

1. Cast Tormod's Crypt by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Tormod's Crypt by tapping and sacrificing it.
4. Activate Krark-Clan Ironworks by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Tormod's Crypt from your graveyard to your hand.
6. Repeat.

This clever loop relies on a recursive exchange of artifacts and historic spells to fuel an unstoppable engine. You begin by casting Tormod's Crypt for zero mana, which triggers Teshar, Ancestor's Apostle and lets you pull Scrap Trawler back from the graveyard. You then sacrifice Tormod's Crypt for its ability and feed Scrap Trawler to Krark-Clan Ironworks, generating colorless mana while the Trawler's death trigger bounces Tormod's Crypt right back to your hand. Because Tormod's Crypt is a historic spell that costs zero, recasting it restarts the entire cycle to generate infinite sacrifices, artifact triggers, and mana.
