Teshar, Ancestor's Apostle + Aether Channeler + Mana Crypt + Bloodflow Connoisseur

Teshar, Ancestor's Apostle

Aether Channeler

Mana Crypt

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur 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 combo lets you leverage Teshar, Ancestor's Apostle and its historic-spell trigger to endlessly loop a creature in and out of the graveyard. By casting cheap artifacts like Mana Crypt, you trigger Teshar to continually resurrect Aether Channeler, whose entrance ability bounces your artifacts right back to your hand. Meanwhile, Bloodflow Connoisseur stands ready to sacrifice Aether Channeler whenever needed, converting the churning cycle into endless deaths, enters-the-battlefield triggers, and a rapidly growing pile of +1/+1 counters.
