Sorry if this is a stupid question. I just really like using some of these banned Pokemon and want to know if I can use them in Showdown during the two months I can't use them in Battle Stadium.
Yes, the bans will apply. I asked on the VGC Showdown! room, and someone confirmed it. I unfortunately could not get the screenshot, but if you don't believe me, feel free to ask on the VGC Showdown! room.
Hope I helped!
