I just did a challenge run (in challenge difficulty). I got some ideas from YurilXes, but the strat might be a bit different.
I went for 13 instead of 11 because i think it might make the 97 fight easier. Instead, the 19 fight will be harder.
I defeated these prime stone masters in order, and here's my decks:
1: just lose, whatever
2: use all special powers
7: all 2s
13: 7, 7, 7, 2, 2, 4, 4, 4, 6, 10
19: 7, 7, 7, 4, 4, 4, 4, 4, 3, 5
23: the same as 19.
37: all 1s
31: 7, 7, 7, 4, 4, 4, 4, 4, 19, 19
43: 7, 7, 7, 4, 4, 4, 4, 4, 15, 31
53: 7, 7, 7, 8, 8, 8, 19, 31, 31, 31
67: the same as 53, or change the three 7s to 2,3,5
71: the same as 53, or replace 19 with 23
79: 71, 71, 71, 56, 56, 56, 43, 43, 31, 31
97: 13, 13, 43, 43, 43, 67, 67, 67, 23, 23
