Deep Cavern Bat does not work as it should in game. It acts a reveal when it is a look. After the player who controls bat takes the card the cards should not remained revealed. When you look it is not public info to the game. I understand you and your op know what is there but that is not how looks work. It is programmed as a reveal. Please fix this as this card has been out for many years now and no one seems to notice/care that this is not correct.
