Teshar, Ancestor's Apostle + Scrap Trawler + Ravenous Intruder + Dark Sphere

Teshar, Ancestor's Apostle

Scrap Trawler

Ravenous Intruder

Dark Sphere

How it works

1. Cast Dark Sphere by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Dark Sphere by tapping and sacrificing it.
4. Activate Ravenous Intruder by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Dark Sphere from your graveyard to your hand.
6. Resolve the Ravenous Intruder ability.
7. Repeat.

This clever recycling loop relies on Teshar, Ancestor's Apostle and Scrap Trawler working in tandem to continuously resurrect your cheap artifacts and creatures. By using Ravenous Intruder to sacrifice Scrap Trawler, you trigger the Trawler's ability to pull Dark Sphere right back to your hand, allowing you to recast it and trigger Teshar all over again. Dark Sphere serves as the perfect low-cost historic spell to fuel the loop while also giving you a way to cycle back into your hand, ultimately leaving you with an infinitely massive Ravenous Intruder and boundless artifact and creature triggers.
