i think so too and the known setting is 10 can be sent though game sync and thats pretty good
and i have sent 2 at a time already and i have maybe sent 3 at a time already(that's with extra pokemon from Gamefreak)
thats wrong Nintendo dosen't have all rights to do everything on pokemon games, there just the format that pokemon games are made, Gamefreak aren't getting off there buts to fix it
the "export cookies" did better than the one in the video
