Why is batton pass a flat ban? In one day I can freely use my just bought smeargle like that and I wake up on the other day and it is just banned? Make it a clause, like the Freezing clause since it is permited on Real pokemon tournamens. or at least make something like only one pokemon with batton pass on party (to avoid chains). Please answer since I cant find a way to post into the suggestion topic.
