Teshar, Ancestor's Apostle + Aether Channeler + Sol Ring + Carrion Feeder

Teshar, Ancestor's Apostle

Aether Channeler

Sol Ring

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Aether Channeler, putting a +1/+1 counter on it.
2. Activate Sol Ring by tapping it, adding CC.
3. Cast the other artifact with MV<=1 by paying at most 1.
4. Teshar triggers, returning Aether Channeler from your graveyard to the battlefield.
5. When Aether Channeler enters the battlefield, it triggers, returning Sol Ring from the battlefield to your hand.
6. Activate Carrion Feeder by sacrificing Aether Channeler, putting a +1/+1 counter on it.
7. Cast Sol Ring by paying 1.
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 delightful loop relies on casting cheap historic spells to repeatedly leverage Teshar, Ancestor's Apostle's ability to pull small creatures straight from your graveyard. By utilizing Aether Channeler's versatile entry trigger to bounce your own permanents back to your hand, you can alternate between recasting Sol Ring and a cheap artifact to keep the chain going. Meanwhile, Carrion Feeder acts as the designated sacrifice outlet that fuels the graveyard-to-battlefield cycle while growing larger with infinite +1/+1 counters.
