Using Patrick Page's Easy Money classic, Greg and Karl applied this brilliance to Hundy 500 and Heiny 500. They then independently conceived a new way to further the gimmick as a covert switch instead of an overt change. This secret undercover handling opened up many new possibilities in magic and mentalism. Included are six mind-blowing routines of secret switchery by Greg, Karl, David Gripenwaldt and Anton James. Speaking of mentalism, we know what you're thinking... Switchcraft can be done with any denomination of any currency anywhere in the world!
