Replacing 3DS Library

After about a year of trying to find my DS/3DS library, it's so nice to have my library again. I ordered a good chunk of my old library, all my Pokemon games for the 3DS as well as all of gen 7, and the copy of Sun I ordered had a living dex on it! No way I'm deleting this, I'm using it to get a team together for my Gen 7 games. They had some good shines too. They had all the Unown on there, all shinies, so I think those are hacked. But still, this person had event Pokemon and was a shiny hunter, so I'm keeping it so I can't delete their old profile. No way I can delete their progress. Too much respect for them.
