Teshar, Ancestor's Apostle + Scrap Trawler + Phyrexian Altar + Welding Jar

Teshar, Ancestor's Apostle

Scrap Trawler

Phyrexian Altar

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 Phyrexian Altar by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Welding Jar from your graveyard to your hand.
6. Repeat.

This elegant recursion engine turns low-cost artifacts into an endless fountain of resources, fueled directly by Teshar, Ancestor's Apostle and its knack for reanimating small creatures whenever you cast a historic spell like Welding Jar. As you sacrifice Welding Jar to regenerate itself or an artifact, Scrap Trawler sits on the battlefield to catch it on the rebound, returning Welding Jar to your hand the moment it hits the graveyard. Meanwhile, sacrificing Scrap Trawler to Phyrexian Altar generates the colored mana needed to recast Welding Jar while feeding the Scrap Trawler's own recycling triggers, creating a closed loop that floods the battlefield with infinite triggers and mana.
