Yeah the trick its pretty good. Well done

A few bit of advice though.
I think you need to speed up your patter, just get to the point you know? So instead of explaining the whole story of how the card must be shy and it's disguised it's self as the King of Diamonds etc. you should just say something like (when they react to the king of diamonds, "oh no you see it is your card but it's just shy", then do the change, "you see it was disguising it' self". That's all you need. I like to write my patter down and think about what needs to be in there. I think this is important, as the spectators may get bored if you do a lengthy intro to a trick.
I like the concept, but I think you would have to do it directly after an ambitious card routine (or part of one), so they get the idea that it is supposed to come to the
top, without you having to explain. You could have the card "hiding" in your pocket, or under the card box or something too, just expanding on the patter and having fun with it.
Nice video though mate, good luck with it!
