hmm
wayne said that the two cards could be from two decks, but he never said they had to be the same.
so, my guesses are:
1) three of spades + four of diamonds
2) seven of clubs + king of diamonds
3) jack of hearts + four of spades
now i dont know if i get a fourth guess or not, but in case i do,
4) six of spades + seven of spades
c'mon c'mon big money, big money...
