Teshar, Ancestor's Apostle + Scrap Trawler + Welding Jar + Bartolomé del Presidio

Teshar, Ancestor's Apostle

Scrap Trawler

Welding Jar

Bartolomé del Presidio

How it works

1. Cast Welding Jar by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Welding Jar by sacrificing it.
4. Activate Bartolomé del Presidio by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Welding Jar from your graveyard to your hand.
6. Resolve the Bartolomé del Presidio ability.
7. Repeat.

This loop sets up an ingenious recycling engine driven by Teshar, Ancestor's Apostle, whose historic spellcasting trigger plucks Scrap Trawler straight from the graveyard whenever you play an artifact. To keep the gears turning, Welding Jar provides a zero-mana historic spell to jump-start Teshar while doubling as a recyclable loop piece, and Bartolomé del Presidio acts as the sacrifice outlet that enables Scrap Trawler's own ability. Each time you sacrifice Scrap Trawler, its modular return clause fetches the Welding Jar back to your hand so you can cast it all over again, generating infinite sacrifice and death triggers, storm count, and massive +1/+1 counters on Bartolomé del Presidio in the process.
