This is not self-working. You will need to be familiar and proficient with a few difficult sleights in order to use most of these routines.
I would recommend checking out a DVD on color changes and card sleights before buying this.
An old DVD that is very informative is Hot Shot Color Changes by Ben Salinas: https://www.penguinmagic.com/p/1599
It is a very complete collection for learning classic color changes. Armed with the information in that video and the gaffs in this deck you will have a bunch of great material.
