I use a deck of Madame LeNormand cards, these were widely used in France, she was the psychic to Napoleon and the court of France.
I am also an Astrologer, Numerologist and read palms.
On my TV show, which is in it's 15th year on Channel 20, Long Island, I read over the phone without cards. The show is the longest running psychic call-in show in America today, Thursday nights at 7 - 8 pm.
