I'm quite sceptical about empirical values since you can get as many experiments you want but the limit of probabilities approaches
(infinity).
So due we don't have endless time you can get sure datas from maths.However maths provides sure headache.
*every case of probability happens in 5(6x5 deck)x 5(6x5 ai)=25 cases
(it still doesn't mean that after 25 games you won't have a sure review of the deck yet, because often cases happen twice during testing.But if you run a test for every combination(outside elements) you will be sure about how the deck behaves)
If you want to test easier the deck give the ai deck with limited quanta and many copies like this
4vj 4vj 4vj 4vj 4vj 4vj 4vl 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vj 4vl 4vl 4vl
USEM by jmdt is quite straightforward so (2/30 10/30 6/30 6/30 6/30)
ai 3 currently has a rough medium of 40 cards, almost 8kind of cards and 13decks
(6+6+1+10+2_30)(8_40)(13)=520cases
error esteem (2/3+2/3)(8(1/40))(13)=52/15=<3.5
So 524 tests
I'm going to study another little maths...
