So I got an used copy of Pokemon Y shipped yesterday with my New 2DS, and for my surprise the previous owner left a 400+ hours save file on it filled with a lot of legendaries (even shiny versions of X and Y face pokemons) from all gens and even most of the event exclusive pokemons except Mew and Celebi.
The game doesn't seems to be hacked as he don't have multiple masterballs or anything like that and have traded a lot with players from all over the world, he even has a few pokemon named such as (no thanks, yes please, that's all I got) that he probably used to comunicate with players all over the world for trade.
Now I don't know if I just delete it and get to play or if I should try to save at least those rare pokemons for myself.
Though as I don't have another 3DS I wouldn't be able to change it to another pokemon game anyway, do I have a workaround for it? Will that paid pokemon bank app help?
How often are those mystic pokemon distributed? Can I get them here in Brazil as physical events just never happen here?
Thanks in advance.
