Technomancer + Krark-Clan Grunt + Auton Soldier

Technomancer

Krark-Clan Grunt

Auton Soldier

How it works

1. Cast Technomancer by paying 5.
2. When Technomancer enters, it triggers, causing you to mill three cards and return Auton Soldier from your graveyard to the battlefield as a copy of Technomancer.
3. When Auton Soldier enters, it triggers. Holding priority, activate Krark-Clan Grunt by sacrificing Auton Soldier.
4. 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.
5. Repeat from step 3.

This clever loop turns a single Technomancer into a self-sustaining engine by utilizing Auton Soldier to repeatedly re-enter the battlefield as an exact copy of the original, milling your library and churning out endless creature and artifact triggers in the process. While Krark-Clan Grunt serves as the necessary sacrifice outlet to bin the clone and fuel the cycle, its ability to grow in power also benefits from the infinite sacrifices. Because Auton Soldier enters as an artifact copy of Technomancer with the aid of its own clone effect, it continuously resurrects itself directly from the graveyard without ever needing to touch your hand.
