No they weren't trying to ban you they were trying to remove your deck because the deck that you remixed was a remix of a deck that broke one of the community guidelines rules so they had to delete your remix with it or else it wouldn't really worked out and they would have to suspend you if you didn't and it was public but since you didn't have it public you aren't going to get suspended nor are you going to even get a warning because that is not a problem you just remixed random deck
