As far as letting your party know what card you've cast on them, it really shouldn't matter to much except for Spear, since they'll know they can use their cooldowns and have a reduced timer on them. Other then that the rest of the cards just add passive bonuses that help out in their normal rotations.
That royal road effect on spear and ewer has been switched.
