Teshar, Ancestor's Apostle + Scrap Trawler + Delif's Cone + Phantom Train

Teshar, Ancestor's Apostle

Scrap Trawler

Delif's Cone

Phantom Train

How it works

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

This loop is an exquisite engine of perpetual motion, sustained by the intricate interplay of graveyard recycling and historic spellcasting. Every time you recast Delif's Cone, Teshar, Ancestor's Apostle triggers to fish Scrap Trawler out of your graveyard, readying the board for the next iteration. Meanwhile, Scrap Trawler's passive ability turns the sacrifice of Delif's Cone into a reclamation tool, returning the artifact right back to your hand. Phantom Train serves as the necessary outlet for this recursion, consuming Scrap Trawler as a sacrifice to fuel its own animation and grow with +1/+1 counters while cleanly sending the Trawler back to the graveyard to be caught by Teshar's next historic trigger.
