Teshar, Ancestor's Apostle + Carrion Feeder + Mirkwood Nurturer

Teshar, Ancestor's Apostle

Carrion Feeder

Mirkwood Nurturer

How it works

1. Cast an artifact in your hand by paying 0.
2. Teshar triggers, returning Mirkwood Nurturer from your graveyard to the battlefield.
3. When Mirkwood Nurturer enters, it triggers, returning another artifact that can be cast for 0 from the battlefield to your hand.
4. Resolve the artifact spell cast in step 1.
5. Activate Carrion Feeder by sacrificing Mirkwood Nurturer
6. Repeat.

This looping engine relies on Teshar, Ancestor's Apostle to continuously recycle small permanents, transforming the simple act of casting free artifacts into a boundless source of value. Each time you replay your zero-mana artifact, Teshar triggers to pull Mirkwood Nurturer straight out of your graveyard, whose own entry ability bounces that very same artifact right back to your hand. Meanwhile, Carrion Feeder acts as the designated executioner, gladly consuming Mirkwood Nurturer so the entire sequence can reset from the graveyard all over again.
