here's something i didn't know.

"The standard 52-card deck is often augmented with jokers or even with the blank card found in many packaged decks. In France, the 32-card piquet stripped deck is most typically used in cartomantic readings, although the 52 card deck can also be used. (A piquet deck can be a 52-card deck with all of the 2s through the 6s removed. This leaves all of the 7s through the 10s, the face cards, and the aces.)"
