Anytime I see a deck of cards I want to perform this trick. Don't let the simplicity of the method full you...this trick melts minds!

I've done this effect 17 times and I love it. The only downfall is you can't do it outside in any kind of wind. It is also long with an avg. Running time of 6-8 minutes. Peter tells you ways to shorten it but I think that take's away from the overall impact. I'm very happy with the effect.

This has fooled more people in a short while, that its going in my repertoire
However I changed the ending slightly to suit me

I brought this trick and it was very nice. Takes only minutes to learn, and Nardi teaches a wonderful reset, and also multiple performance techniques for different types of magicians rather parlor or stage. I enjoy this trick because after its done you can use the deck for any other trick, you end that clean.

Five stars, I'd rate it 'Easy' difficulty for new magicians, just brought it today learned it in a hour and already people are loving it to those I perform to!

Yea, this is pretty much real magic, so just buy it.

The DVD is thorough and has multiple routine ideas. It also has some added bonuses about how to shuffle cards.

It comes with two different prediction cards so you can shake things up a bit. It also comes with a written document that has a bit of an update to the effect, I guess it was thought of after the DVD was pressed. The effect as taught on the DVD is pretty much perfect anyway so it's just a thoughtful added touch.

This is completely self working and the video did fool me. I'm usually pretty good at figuring card effects out. This one I almost had after watching the demo video a few times but was just missing something and ultimately ended up being stumped. It made me laugh how simple it actually was once I had it in my hands though.

This is a different method than I have seen for a self working prediction and I highly recommend it.

It really has been a great few weeks for magic releases as well, with tricks like this one, Little Door and Shuffled. Good times, good times indeed.

I really like this effect. It's fun, easy, and entertaining.

The Butterfly Effect is an extremely entertaining routine that is very easy and can be done with any deck that you already use. I havery been using Andy Nymans Code Deck. This affords me the option to continue with other mentalism effects strait away.

Very nice effect. I was sceptical that it would look as good as the trailer. It was even more powerful than I expected. There is several reveals to choose from. Lots of good instruction and explanation. Takes a little setup but easy to learn. I'm not great with cards but was able to perform in minutes. Good value.

This is great trick self working I like the fact that the spectator does his own choices and still get a direct hit great buy

I love this trick. easy to set up and fun to do. has become a staple in my repertoire.
