Teshar, Ancestor's Apostle + Scrap Trawler + Blasting Station + Welding Jar

Teshar, Ancestor's Apostle

Scrap Trawler

Blasting Station

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. When Scrap Trawler enters, Blasting Station triggers, untapping Blasting Station.
4. Activate Welding Jar by sacrificing it.
5. Activate Blasting Station by tapping it and sacrificing Scrap Trawler.
6. When Scrap Trawler dies, it triggers, returning Welding Jar from your graveyard to your hand.
7. Resolve the Blasting Station ability.
8. Repeat.

This elegant loop centers on the recursive power of Teshar, Ancestor's Apostle, which uses the casting of historic spells like Welding Jar to continuously pluck Scrap Trawler back from the graveyard. As Scrap Trawler hits the battlefield, Blasting Station's triggered ability untaps itself so it can continually sacrifice creatures. Whenever Scrap Trawler is sacrificed to feed Blasting Station's damage output, its own ability triggers to return the spent Welding Jar right back to your hand, ready to be recast and restart the entire cycle.
