I have been doing card magic on and off for around 8 years now and I have studied books such as Expert at the card table and Royal road to card magic almost completely front to back. I am looking for a bit more of a challenging book that has much more advanced and difficult sleights. Only problem is that I only have 25 dollars to spend on the book. I am aware thats not a lot to spend considering most of these types of books are upwards of 50 dollars but any response would be greatly appreciated. Thanks!
