You are assuming that if you find a card you have to play it, because you saw that Forced: there. You are wrong according to James. You badly misinterpet the ability, have you understood that by now?
Your argument is naive because this is exactly the kind of game where honesty should be forced by the rules. It is highly competitive and will be played in tournaments against people you don't know. When playing with your buddies everything's OK, but try to bring your fair play gospel to a room of prize-hungry competitive strangers and you are in for a rough awakening...
