Teshar, Ancestor's Apostle + Aether Channeler + Mana Vault + Phantom Train

Teshar, Ancestor's Apostle

Aether Channeler

Mana Vault

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Aether Channeler
2. Activate Mana Vault by tapping it, adding CCC.
3. Cast the other artifact with MV<=2 by paying at most 2.
4. Teshar triggers, returning Aether Channeler from your graveyard to the battlefield.
5. When Aether Channeler enters the battlefield, it triggers, returning Mana Vault from the battlefield to your hand.
6. Activate Phantom Train by sacrificing Aether Channeler
7. Cast Mana Vault by paying 0.
8. Teshar triggers, returning Aether Channeler from your graveyard to the battlefield.
9. When Aether Channeler enters the battlefield, it triggers, returning the other artifact from the battlefield to your hand.
10. Repeat.

This mesmerizing loop relies on Teshar, Ancestor's Apostle acting as your engine, resurrecting Aether Channeler from the graveyard every time you cast a historic spell. As Aether Channeler repeatedly enters the battlefield, its trigger lets you bounce and replay your resources—such as Mana Vault and a cheap artifact—while Phantom Train sacrifices the Channeler to fuel the engine and grow itself into a massive threat. The explosive mana production of Mana Vault ensures you can continually recast your artifacts to keep Teshar triggering this relentless cycle.
