This is nonsense. 52 cards in a deck, all of them are said multiple times. A bit of a desingflaw. Maybe taking the guys and gals who posted the card and play another wheel of fortune.
7 of diamonds, my favourite card since day 1. I actually have a 7of diamonds from one of my first deck proffessional cards.
