Hey I don't really want to get on skype and slowly load the whole convo and everything to tell you this so I'll say it here, 4/6th of your team doesn't handle cele well. YOu have offensive Balloon tran which is a pretty solid check, but if they have earth power it becomes much less so. Land u-turn spam keeps it in check well, but a small change you could make is to try out an expert belt rotom with signal beam. Might help viriz and CO out, or you might be happier with chesto, idk.
