This loop turns a simple sacrifice outlet into a perpetual motion machine by exploiting the interaction between creature death and recursion. While Woe Strider acts as the engine by eating your board for scry triggers, the real magic relies on Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight granting persist to your nontoken creatures, which would normally return them with a debilitating -1/-1 counter. Melira, Sylvok Outcast completely shuts down that downside with her passive ability, ensuring that creatures enter the battlefield completely pristine and ready to be sacrificed over and over again.
