Teshar, Ancestor's Apostle + Aether Channeler + Mana Crypt + Bartolomé del Presidio

Teshar, Ancestor's Apostle

Aether Channeler

Mana Crypt

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio by sacrificing Aether Channeler, putting a +1/+1 counter on it.
2. Activate Mana Crypt by tapping it, adding CC.
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 Crypt from the battlefield to your hand.
6. Activate Bartolomé del Presidio by sacrificing Aether Channeler, putting a +1/+1 counter on it.
7. Cast Mana Crypt 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 Vintage-legal loop transforms Teshar, Ancestor's Apostle into an engine by leveraging historic spell casts to continuously resurrect Aether Channeler from the graveyard. As Aether Channeler enters the battlefield, its versatility allows it to bounce your fast mana or artifacts back to your hand so they can be recast, fueling the chain. Meanwhile, Bartolomé del Presidio provides the necessary sacrifice outlet to send Aether Channeler back to the graveyard while growing larger with every iteration, and the explosive mana acceleration of Mana Crypt helps pay for your spells and keeps the loop spinning indefinitely.
