Thanks for the clarification!
Should I also assume that if some other monster's shadow card gets rid of the attachment during the engaged player's combat phase then the previously snared monster would then attack (and resolve its shadow card)?
i.e. the big scary monster that you thought you wouldn't have to worry about this turn is going to break free from its trap at the worst possible moment and kill some unsuspecting hero...
