You can copy pokemon and items it realy works.
First beat the e4(eleate 4) then once u go to the battel frounter go to battle tower.
Then go to the pc put in the pokemon u want to copy all in a seperit box.
After you did that walk away but not out of the building and press a,b,r,l or just go and put them back with you remember keep that box empty and be for you put them with you save.
Finaly go to the muti link battle when she asks u to save say yes then quicly turn off the game turn it back on check ur party they are there check the box they are there two.
