The Lucky 13 Mystery Box cycles in and out of the store for a price of about 2 diamonds on sale. Each time you open a Lucky 13 Mystery Box, you will be rewarded with a 2nd (and potentially a 3rd and 4th) "roll" which will give you the chance to win one (or more) of the advisor contracts below in addition to one of the other prizes. In other words, you can only achieve a 3rd roll if you win an advisor on the second, and so on for the fourth roll. NOTE: You can ONLY win advisors on rolls after the first; none of the other prizes will be dropped.
