Only 1 card at a time... for 980(?) gold.

Just imagine a lottery with 80 numbered balls in it. You pull only 1 ball everytime you use gold.

If you don't get the number you want, throw away the ball and pay to try again (now only 80-1=79 balls left) until either you get what you want, or you become broke. ;)
