What I usually do is get a full party of eggs, with a Talonflame that has flame body, and I go to the little like pen area in front of the Nursery, and use the Tauros mount to just spin in circles and shit. Then every time i hatch an egg, I go to the daycare lady and instantly switch out the Pokmeon I just hatched with another egg.
Is there a way this could go by even faster? Cus this is already stupidly fast
