Im online and waiting if you still wanna battle, sorry my internet broke and i wasnt sure if you were online and waiting for me as i couldnt see your thread reply.
Plat moves are a different kettle of fish, you don't have to use a AR code to use then on wifi, nintendo have bared the use of the rotom forms on wifi for a reason. At the end of the day your using a hacking device to gain an advantage. You might be added to the blacklist for this.
you should do it, i really want this cleared up for other situations, the rotom was legally obtained so its techinally not a hack, so i cant see a problem with it, its exactly the same situation with platinum moves on dp pokemon
