I've been using the first version of WOW (the face up one) for many years now. its really really
good. HOwever, face down WOW has just opened up so much more possibilities.
Not only is it
amazing to end your ACR, but there are many many more applications for this gimmick. you can make a
deck turn blank, or make it dissapear (using a O*&^ deck), or make signatures/drawings appear and
dissapear on the back of a card, etc etc.
The only thing I would say is that the DVD I got was
terrible. for those who want to explore the many other things possible with this should check out a
companion DVD.
All in all, fantastic gimmick, great quality and very commercial.
