Well, you can counter that with doing up a set of your own using the 'rune' idea. I did my own rune set by getting some of those flattened glass marbles they use in decorative fish tanks, drawing the rune on paper, cutting it out, using Elmer's glue to put it on the flattened back side of the glass, then going over the back & edges with clear fingernail polish (I tried Modge Podge but they stuck together & the paper pulled off--the fingernail polish took care of that entire problem). Just make sure to use good ventilation with the nail polish though or you'll be killing brain cells!
A marble for each card, a bag to put them in, shake & draw your spread!
(Bet they'd sell too!)
