Teshar, Ancestor's Apostle + Scrap Trawler + Extruder + Welding Jar

Teshar, Ancestor's Apostle

Scrap Trawler

Extruder

Welding Jar

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 Extruder by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Welding Jar from your graveyard to your hand.
6. Resolve the Extruder ability
7. Repeat.

This clever loop is orchestrated by Teshar, Ancestor's Apostle, whose flying and historic-trigger synergy rewards you with recurring creature support every time you cast an artifact like Welding Jar. As you replay that Welding Jar, Teshar reaches into your graveyard to pull back Scrap Trawler, creating a recursive engine where the Trawler's death triggers continuously cycle your cheap artifacts back to your hand. Meanwhile, Extruder acts as the sacrifice outlet that fuels the loop, using the sacrificed Scrap Trawler to not only trigger its recovery ability but also distribute infinite +1/+1 counters to your creatures. Welding Jar pulls double duty here as both the cheap historic spell to keep Teshar triggering and the fuel that gets recycled, ensuring the entire assembly line keeps running indefinitely.
