Teshar, Ancestor's Apostle + Scrap Trawler + Bartolomé del Presidio + Tormod's Crypt

Teshar, Ancestor's Apostle

Scrap Trawler

Bartolomé del Presidio

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

This elegant loop relies on Teshar, Ancestor's Apostle acting as your engine, transforming every recast of Tormod's Crypt into a resurrection trigger for Scrap Trawler. As Scrap Trawler hits the graveyard—fed to Bartolomé del Presidio's sacrifice outlet—its own ability triggers to hand Tormod's Crypt right back to you. Because Tormod's Crypt costs zero mana, you can recast it instantly to repeat the cycle infinitely, growing Bartolomé del Presidio larger with every iteration while generating an endless stream of artifact and creature sacrifices.
