Teshar, Ancestor's Apostle + Aether Channeler + Sol Ring + Bloodflow Connoisseur

Teshar, Ancestor's Apostle

Aether Channeler

Sol Ring

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur 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 ingenious loop centers around Teshar, Ancestor's Apostle, whose static ability continuously resurrects small creatures whenever you cast a historic spell. By leveraging Aether Channeler's entry trigger to bounce your mana source or artifacts back to your hand, you create a self-sustaining cycle where recasting those permanents triggers Teshar all over again. Bloodflow Connoisseur serves as the necessary outlet to clear Aether Channeler from the battlefield into the graveyard while growing larger with infinite +1/+1 counters. Meanwhile, Sol Ring provides the explosive mana generation required to repeatedly recast your artifacts and keep the engine turning.
