I’m starting to become dubious since I’ve caught over 30 Clefairys now and not a single one of them is marked, whereas I’ve caught a marked Pikachu on my 6th attempt on a route, not in the Wild Area.
Is it just my bad luck or is it like this for other people?
I know Serebii says that all wild Pokémon can be marked but I prefer experience as the source here.
Thanks!
