Maybe you can try to at least not get all your stones frozen on the first turn and use more 2s. 

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
