Good starting point for exploring GD deck. Includes short history, brief description of the cards, Book T, The Opening of the Key, and Wang's deck pictures.
However it is only what it says in the title - an introduction, so if you are looking for more detailed information on GD deck this is not a book for you. If you have Ciceros' cards, the mini-book attached to their deck covers pretty much the same that this one.
