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.
When Auton Soldier enters, it triggers. Holding priority, activate Woe Strider by sacrificing Auton Soldier.
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.
Repeat from step 3.
This clever loop turns Technomancer into a self-sustaining resurrection engine by pairing it with Auton Soldier, which enters as an exact copy of Technomancer while adding the artifact type to fuel the recursion. Every time Auton Soldier enters the battlefield, its triggered ability lets you replay Technomancer or another copy from the graveyard, but you immediately sacrifice it using Woe Strider's activated ability to keep the graveyard clean and trigger perpetual scrying. Because Woe Strider's sacrifice outlet acts as an instant-speed safety valve, you can safely loop these enters-the-battlefield and leaves-the-battlefield triggers infinitely to mill your entire library and generate boundless death and sacrifice triggers.
