Teshar, Ancestor's Apostle + Scrap Trawler + Ravenous Intruder + Tormod's Crypt

Teshar, Ancestor's Apostle

Scrap Trawler

Ravenous Intruder

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 Ravenous Intruder by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Tormod's Crypt from your graveyard to your hand.
6. Resolve the Ravenous Intruder ability.
7. Repeat.

This clever loop turns graveyard recycling into an engine of endless power by leveraging Teshar, Ancestor's Apostle and Scrap Trawler in tandem. When you cast Tormod's Crypt, Teshar triggers to pluck Scrap Trawler straight from your graveyard, while Ravenous Intruder stands ready to sacrifice that Scrap Trawler to its own ability. The brilliance of Scrap Trawler is that its death trigger retrieves an artifact with a lesser mana value—namely, the Tormod's Crypt you just sacrificed—putting the free-to-cast artifact right back into your hand so the whole cycle can begin anew.
