How it works

1. Cast Lion's Eye Diamond by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Lion's Eye Diamond by discarding your hand and sacrificing it.
4. Activate Phantom Train by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Lion's Eye Diamond from your graveyard to your hand.
6. Resolve the Phantom Train ability.
7. Repeat.

This intricate recycling engine uses Teshar, Ancestor's Apostle as its beating heart, turning every historical spell cast into a resurrection tool for Scrap Trawler. By sacrificing Lion's Eye Diamond for mana while discarding any clutter in your hand, you feed the mana needed to keep the chain moving while triggering Scrap Trawler to hand the Diamond right back to you. Meanwhile, Phantom Train acts as the necessary sacrifice outlet to bin Scrap Trawler and restart the loop, growing stronger with every iteration. Together, these pieces seamlessly convert quick-fire artifact sacrifices into infinite colored mana, an infinitely massive vehicle, and a boundless storm count.
