Teshar, Ancestor's Apostle + Scrap Trawler + Lotus Petal + Lithatog

Teshar, Ancestor's Apostle

Scrap Trawler

Lotus Petal

Lithatog

How it works

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

This engine turns a humble zero-mana artifact into an infinite recycling loop by using Teshar, Ancestor's Apostle as the resurrection engine for Scrap Trawler. Every time you recast Lotus Petal, Teshar triggers to bring Scrap Trawler right back to the battlefield, ready to be sacrificed. When you feed Scrap Trawler to Lithatog's sacrifice outlet, the Trawler's own ability triggers to hand the Lotus Petal straight back to you. This creates an endless cycle of artifact entry, death, and mana generation that can also pump Lithatog into an infinitely massive threat.
