Technomancer + Megatog + Auton Soldier

Technomancer

Megatog

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 Megatog 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 is ignited by casting Technomancer to resurrect Auton Soldier from your graveyard as a copy of another Technomancer, setting up an endless recursion fueled by the stack. While the copied Technomancer's entrance trigger waits to resolve, Megatog steps in as the ultimate sacrifice outlet, sending the cloned artifact creature straight to the graveyard just in time to be brought right back. This seamless cycle repeats indefinitely, triggering a massive wave of enters-the-battlefield and death triggers while pumping Megatog into a colossal threat.
