card manipulation -- too much proving???

although card manipulations can look pretty if done properly, but the very nature of the manipulations make them a non-magical effect and more like jugglery. perhaps to a first time viewer it might appear like a very very perplexing puzzle but any ``experienced" audience would probably pass these on as mere digital dexterity and juggling and not magic. i think the amazement factor is lost upon the audience and upon that very loss the magical nature goes too.
