If you are looking at your cards in your deck, it’s a key. It means that you have locked that card and cannot be seen by other players.It’s a good idea to them as you can’t acidentally sell them or trade them or mess them up in anyway. Cards in your Colosseo line auto lock and have to be removed from Colosseo Line to unlock them.
