We'll have to agree to disagree on that one I think. There are some effects where the magic speaks for itself - say a colour changing backs routine - but I think careful attention to the premise and presention of your effect would enhance, rather than take away from it.
We can't do "wizard magic" - not really. All magic in the fantasy world has an underlying purpose - a goal, a logic to it. As magicians in the REAL world, we should strive for the same consistency - "random acts of magic" come off as stunts more than anything else.
With just a little twist, your "blah blah" presentation could be turned into something very interesting I think. The difference is that the words you have chosen imbue the "ink" with the power, rather than yourself. If you use "magic" to cause the ink to teleport, then we're still talking magic, not science.
You'll note as well that this is not what I proposed either; I'm not a fan of convulted patter lines. The card is selected and lost in the deck. You cut the deck, finding a card - the ace of spades; not the selection. "I will use the spade to find your card" - and do any kind of location you like (a pass comes to mind to centralise the ace with the selection). Remove the ace and show the selection. Placing the spade to one side - or a pocket - you then proceed into your trick, using the spade on the card case instead. No weird and wonderful patter lines in there I think.
Taking this further, you could use a simple switch of the ace and the selection once the first phase is over, placing the selection to the side instead of the ace. Then do your trick, showing that the spade from the case has found one card...the ace of spades - which the audience thinks is in your pocket/on the table/between their hands/whatever. Reveal the selection and you've added a transposition, perfectly motivated by the initial trick of using the ace to find the card.
There's nothing necessarily wrong with "just doing it" either of course; just be careful not to dismiss anything too soon. If there's one thing I've picked up from my own experience and the work of others, it's "never stop thinking"; just today I picked up a wonderful little sandwich switch from "Power Plays" which tidies up the handling one of my strongest tricks that I use all the time - and now it'll be that little bit better because I'm still open to ideas on it, a good couple of years on from when I first put it together.
It's been my experience that the most important part of the creative process is the presentation, patter and premise of your tricks, followed by the most elegant handling solution you can come up with meeting your requirements regarding setup, practicality and context. You've got a good method on the go there, clearly, because you've got me fooled and that isn't too easy! Unable to judge you on the rest obviously from that video, but maybe our little exchange provided you with food for thought.
