This elegant loop centers on the twilight side of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, whose static ability grants persist to your other nontoken creatures, ensuring that when Mindless Automaton hits the graveyard, it immediately returns to the battlefield. Woe Strider acts as the sacrificial engine that fuels this recursive cycle while letting you endlessly sculpt your draws with its scry ability. Because Mindless Automaton's dying triggers are caught and reset by the continuous effect radiating from Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, you can repeat the sacrifice indefinitely to generate boundless entries, exits, and death triggers.
