in my pokemon x game 5 pokemon from the box disappeared (mudkip, blaziken, torchic, squirtle, blastoise) and with them the blazikenite and blastoisite i don't want to have lost those mega stones forever!
my 3ds is used only by me and i obviously can't even think of trading pokemon with megastones
well i gave the 3ds to my brother to let him play pokemon y but pokemon x was in my room
i watched the diary and the game wasn't played in that period
