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

Teshar, Ancestor's Apostle

Scrap Trawler

Megatog

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

This ingenious loop uses Teshar, Ancestor's Apostle as the ultimate engine, reviving Scrap Trawler from the graveyard every time you cast a historic spell like Welding Jar. Once your artifacts are in play, you can sacrifice Welding Jar to its own regeneration ability and use Megatog to eat Scrap Trawler, which triggers Scrap Trawler's passive ability to pull Welding Jar right back to your hand. With Welding Jar ready to be recast, Teshar triggers all over again to loop Scrap Trawler endlessly—pumping Megatog to lethal proportions while generating an infinite stream of artifact and creature triggers.
