I'm not a very big magic practitioner, though I do have some small divination practices. Cartomancy is one of them, and I have adopted a unique style involving a standard 52-card French-suited deck. You can include or exclude the Jokers on your personal choice; this little reference of mine will exclude them.
I tend to base the four suits on the classical four elements, the humors, or any other set of four that's relevant to the reading at hand.
That aside, I tend to circle nearby numerology and even traditional tarot methods of reading the pip-cards. Face cards are the "major arcana" in a sense, and could be used EITHER as 11-13 or as particular personality traits [ie Queens indicating gracefulness or gentility].
