Technomancer + Blasting Station + Auton Soldier

Technomancer

Blasting Station

Auton Soldier

How it works

1. Cast Technomancer by paying 5.
2. When Technomancer enters, it and Blasting Station trigger.
3. Resolve the Blasting Station trigger, untapping it.
4. Resolve the Technomancer trigger, causing you to mill three cards and return Auton Soldier from your graveyard to the battlefield as a copy of Technomancer.
5. When Auton Soldier enters, it and Blasting Station trigger.
6. Resolve the Blasting Station trigger, untapping it.
7. Holding priority, activate Blasting Station by tapping it and sacrificing Auton Soldier.
8. Resolve the Auton Soldier trigger, causing you to mill three cards and return Auton Soldier from your graveyard to the battlefield as a copy of Technomancer.
9. Repeat from step 5.

This elegant loop leverages Technomancer's entrance trigger to constantly resurrect key pieces from the graveyard, utilizing Auton Soldier entering as a fresh copy of Technomancer to keep the cycle going. Because Auton Soldier enters as an artifact creature with a combined mana value well under six, it can immediately loop itself back out of the graveyard whenever it hits the bin. Meanwhile, Blasting Station acts as the engine's primary outlet, using its static ability to untap each time a creature enters the battlefield so you can sacrifice that same creature for infinite damage.
