Let me start off by saying that I bought this direct from Vinny Sagoo since penguin magic listed this as discontinued. This is such a clever twist on an classic. You only have the five special cards. No flaps, nothing to ditch. No switches. Nothing! What you see in the video is what you get and need for the effect. This trick is great in person but also works on social media since it is a free choice. The spectator can think of any card! People seem to really like this trick, I feel like it could pass for a mentalism trick since you "read their mind", but it is still just a card trick. My advice is to cover the cards in your hands instead of going behind your back, that way people don't think you are switching the cards out. Plus making a single card turn over in your closed hands is more magical. Good luck!
