So I have been playing PRO on and off but lately a lot. I've been reading different posts about what legendaries are catchable and what are not like Mew, Celebi and the legendary Beasts from events/tournaments. Most of the posts were pretty old and I was wondering if anyone had like a list of all the obtainable legendary Pokemon? One the is new or just something so I know if there are any new legendary Pokemon you can catch. Thnx :D
