This is a pretty good trick, but be aware that the learning curve is pretty huge. Even if your used to card magic. You have to learn a number of techniques which feel quite akward at first. But if you put in the practice, the effect is magical, plus you can fool all those haters who say they know how the invisible deck is done.

This trick is not as hard as i thought, but take time to perfect it. Would recommend to anyone!! Also, there are a bonus section which is memorising a deck trick. That's quite cool too!
definately worth the price and it worth more attention!!
