Teshar, Ancestor's Apostle + Scrap Trawler + Krark-Clan Grunt + Welding Jar

Teshar, Ancestor's Apostle

Scrap Trawler

Krark-Clan Grunt

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

This loop relies on Teshar, Ancestor's Apostle acting as the engine's heartbeat, turning every cast of a historic spell into a resurrection tool for low-mana creatures. When you cast Welding Jar, Teshar triggers to pull Scrap Trawler back from the graveyard, setting up a recursive recycling plant. By utilizing Krark-Clan Grunt to sacrifice Scrap Trawler, you trigger the Trawler's ability to bounce the Welding Jar right back to your hand, ready to be recast and restart the whole cycle. Meanwhile, the Welding Jar you keep sacrificing can also be used to regenerate your artifacts if needed, while the Grunt grows infinitely powerful with each sacrifice.
