This is a false shuffle that is basically a Zarrow Shuffle for strolling magic. the Zarrow requires a table so obviously that won't work for strolling magic. This is not for beginners, but intermediate magicians should be able to perform this with quite a bit of work. This isn't easy. If you can't perform it smoothly then you aren't ready to perform it. But once you have you will have a powerful tool.
The instruction is very good and every subtlety and detail is covered in depth.
