I just got the wonderful new Symbology Deck ... it uses symbols and four colors and is a 52 card pack ... pack is well made and marked as well .. a great alternative to playing cards and you can do memdeck routines as well!
below is from the web site http://symbology-deck.com/entire4.htm
The science of signs working for you, Symbology is a system like no other. It allows you to do just about any card trick you can think ofmental, predictive, sympathetic, transposition, mind readingwithout using playing cards. Its a new angle for close-up magicians, a revolutionary opportunity for cold-readers and a mentalists dream come true!
