Technomancer + Goblin Bombardment + Auton Soldier

Technomancer

Goblin Bombardment

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 Goblin Bombardment 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 relies on Technomancer's entrance trigger to repeatedly resurrect Auton Soldier from the graveyard as an exact copy of Technomancer itself. Because Auton Soldier enters the battlefield over and over, its own entering trigger goes on the stack, allowing you to seamlessly sacrifice it to Goblin Bombardment in response. Each iteration fuels the continuous cycle of self-milling, dying, and re-entering, letting Goblin Bombardment effortlessly convert this endless stream of sacrifices into fatal damage to any target.
