you get at least 1 token (up to 4, but heavily weighted toward 1); you can exchange that token up to two times for a full 92 player in sets thats auctionable; even after 2 times, there's another set that only requires a token plus 4 83-84s and is unlimited
The 2, 82+s which are plussing alot (got a bunch of 87s and 88s) are just gravy
I did the set 3 times, only got 1 token each time, and sold the 92s for 800k each and the other stuff for about another million total.
