I was being nosey on the serbii website, I was looking current Pokemon on Pokemon sword and shield. Apparently, there is a mew on the list. Is that mean, mew is not an event Pokemon?
I just found the page.I think what they mean is that it’s possible to have Mew in game, but they probably won’t make it obtainable through normal gameplay.
Mew can be both an event Pokémon and non-event Pokémon, it just depends on your perspective. To get Mew, you have to hook your Pokeball Plus to the S&S game.
