This is a very nice effect in my opinion. it can be done with any deck of cards jacob smith goes into great detail of how the trick works. its not self working but its not hard at all. you the magician do handle the cards just a few times but it all seems very fair. for this effect presentation is the key. there is one sleight used towards the end of the effect to make it all happen but it flies by the spectators and happens on the off beat and its very quick. I will be working on this and will for sure be performing this effect he also teaches you a bonus effect which is pretty neat! is it worth the 12.95? in my opinion i would of paid 9.95 for it in all honesty. but its still a good effect.
