I was playing a game and it was the top of the turn, and I controlled no monsters on board, just Yummymusment Minginon, and It wouldn't let me activate Obedience Schooled, I was playing against blue-eyes, and it had been set on board by thrust then bounced back, so maybe I can't read, but I belive it may be a bug.
