You give them a choice of any prospect, then you get 3 names that are untouchable. They make their 2nd selection, and then you get 10 more names to take off the board, and after their 3rd selection, you get another 10 untouchables. They end up with essentially the number 1, number 5, number 16, and number 27 in the system. Only caveat, the first two picks can't both be pitchers. Pretty simple.
