For advance books:
Art of Astonishment Vol 1-3 (I have not read it,but I am going to soon)
Earnest Earick By Forces Unseen. (I have not read it, and probably never will just check the price tag)
Edward Marlos Revolutionary Card Technique(If your into technique)
Card College (3,4,5)
The Expert at the Card Table SW Erdnase.
Art of Astonishment Vol 1-3 (I have not read it,but I am going to soon)
Start with Volume 1. Not necessary advanced card tricks, but very creating and hard hitting effects.
Earnest Earick By Forces Unseen
Out of print (which is why it is so expensive). I don't have this, but understand that it is amazingly advanced.
However, this is one of my favorite magic videos:
Edward Marlo's Revolutionary Card Technique
Also out of print (although you can buy individual chapters at lybrary.com or Magic Inc.).
Card College (3,4,5)
Yeah, that is your best bet... assuming you have Volumes 1 and 2
The Expert at the Card Table SW Erdnase.
I'm not a big fan, but if you are interested, get one of the annotated versions such as Darwin Ortiz's Annotated Erdnase or Vernon's Revelations.
Actually, that is one of the easier things to do on Trilogy... at least for me.
I want to learn a few advanced card tricks(slight-intensive) as I think that I am ready for it.
There are a lot more choices. To narrow them down, what have you learned so far and from where and what type of magic interests you?
