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

Teshar, Ancestor's Apostle

Scrap Trawler

Atog

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

This loop is a masterclass in recursive recycling, using Teshar, Ancestor's Apostle as the engine that continuously reanimates Scrap Trawler whenever you cast a historic spell like Welding Jar. As you feed Welding Jar and Scrap Trawler to Atog's sacrifice ability, Scrap Trawler's retriever trigger bounces the sacrificed Welding Jar right back to your hand so you can cast it again. Meanwhile, Welding Jar can also be sacrificed to its own regeneration ability to trigger the Trawler's recursion without even losing the artifact, keeping your graveyard and battlefield in a constant, self-sustaining loop.
