Magic Tricks

The method is kind of clever and you could probably do other things with it combined with other gimmicks or moves but i do not think the preperation is justified by the payoff as a stand alone effect.

I would classify this as not for beginners, at least you would have to know a peek or any other method for gaining secret information so you can verbally divine the information before revealing the prediction (Wich is the intial effect) to get any real spark out of it.

But if you can flawlessly do what i just described i think it would be a great demonstration under the rigth conditions
