I've seen this performed by a friend who runs a magic shop site, and he was very excited about it. I enjoyed his performance of the effect, and although it is true it is gaffed to the hilt, its an easy to perform mind bender for the spec. If someone is not a cardie, it would be a very strong effect to perform when a spec asks to see a card trick. But as i guess you guys have already mentioned, nothing else is possible with the deck. As for the price, I admit it did seem a little high, but when I discussed with guys from my club, you can easily pay £1 for one gimmicked card, so I guess you could say that this effect should cost £52?
Not one for me, but I am sure some will buy and some will enjoy performing it.
