Magic Tricks

This is not a good trick. Here is why: The effect is nothing more than a prediction of a card. There are absolutely endless ways to make this happen (an extremely simple version great for laymen would be some form of Gemini twins). So this trick takes a very common effect with many sure-fire ways to do it that are even cleaner, and adds a somewhat convoluted method to make it happen. Now -- here's the kicker. In the demo, the gimmick is not even used! There is one ending which is completely clean and the gimmick doesn't even come into play. That is the ending included in the demo! On top of that, there are some angle issues (there's a reason why it's oddly filmed from the top). The problem can be obviated with some audience management in terms of where spectator says stop. But otherwise, if spectators are seated, rather than standing above the cards, you will have an issue.
The reason this trick caused excitement (even promoted with the tagline-- "can you figure it out") is that, as noted above, what is demonstrated is the best case scenario which does not even use the gimmick. So, obviously you can't figure out the gimmick if the gimmick isn't used. If you end up buying the trick, it's not a total waste of money as the gimmick you receive is very will made and can have lots of different uses with some creativity (though it's a bit expensive for what you get). Bottom line, terrible method for a common effect that can be done so many better ways, and very misleading trailer. M. Chatelain has some terrific effects but this is not one of them.
