Forum:Shuffling face-downs on the field

My roommate says that if you reveal a face-down card to your opponent and it returns to its original face-down position, you are allowed to shuffle the face-down cards on your side of the field. Is this true and might I have a citation to prove or disprove it? Sorarikukai77 (talk • contribs) 01:27, March 7, 2016 (UTC)
