Myr Retriever + Junk Diver + Blasting Station + Mycosynth Golem

Myr Retriever

Junk Diver

Blasting Station

Mycosynth Golem

How it works

1. Activate Blasting Station by tapping it and sacrificing Junk Diver.
2. When Junk Diver dies, it triggers, returning Myr Retriever from your graveyard to your hand.
3. Resolve the Blasting Station ability, dealing 1 damage to any target.
4. Cast Myr Retriever by paying 0.
5. When Myr Retriever enters the battlefield, Blasting Station triggers, untapping Blasting Station.
6. Activate Blasting Station by tapping it and sacrificing Myr Retriever.
7. When Myr Retriever dies, it triggers, returning Junk Diver from your graveyard to your hand.
8. Resolve the Blasting Station ability, dealing 1 damage to any target.
9. Cast Junk Diver by paying 0.
10. When Junk Diver enters the battlefield, Blasting Station triggers, untapping Blasting Station.
11. Repeat.

This clever loop relies on the recursive synergy between Myr Retriever and Junk Diver, which endlessly pull each other out of the graveyard every time one of them hits the dirt. Blasting Station serves as both the executioner and the engine, converting each sacrifice into a point of damage while immediately untapping itself whenever one of the artifact creatures re-enters the battlefield. Meanwhile, Mycosynth Golem reduces the casting costs of both retrievers down to zero via its incredible affinity for artifacts, ensuring you can replay them for free and keep the slaughterhouse running indefinitely.
