which card is bad for players?????

It's a trivial matter for a combinatorial analyzer to determine.
Single deck/S17/DOA/NDAS/No resplit/1 card to split aces/No surrender/Full peek
First image removes 1 four and 1 five, EV = + 1.1730%
Second image removes 1 two and 1 three, EV = + 0.8017%
EVs are calculated for a player using total dependent basic strategy.
These are exact calculations, so there is no debate.

1. Player always uses total dependent basic strategy - no deviations
2. All possibilities are considered for player and dealer
3. Pushes count as 0.0% EV
4. Dealer and player blackjack on the same hand is the same as a push
5. Losses count as -100% EV
6. Dealer blackjack and no player blackjack is the same as a loss
7. Wins count as +100% EV
8. Doubles: EV is multiplied by 2
9. Splits: More complicated, but if only 1 split is allowed EV is multipled by 2
10. Player blackjacks when no dealer blackjack count as +150% EV
11. The sum of the probabilities of each possibility times its result is the overall EV for a basic strategy player for whatever the shoe composition is. (In this case either a 2 & 3 or a 4 & 5 removed from a full single deck.)
It's a mathematical calculation that considers all possibilities.

good/bad cards? how good and how bad?
Well look at it this way, you can take a card value's % effect of removal and multiply it by the ratio of that card to the cards in the deck. Allow me to illustrate:
2: .4 x 4/52 = 0.03076
3: .43 x 4/52 = 0.033076
4: .52 x 4/52 = 0.04
5: .67 x 4/52 = 0.05154
6: .45 x 4/52 = 0.03462
7: .3 x 4/52 = 0.02308
8: .01 x 4/52 = 0.00077
9: -0.15 x 4/52 = -0.01154
10: -0.51 x 16/52 = -0.156923
A: -0.04538 x 4/52 = -0.04538

i not tolking obut wich situation is good when you removed 2,3 or 5,6
i tolking obout wich gard is beter for players
and dealer mo times bust 6,5 dem2,3
456 it is god card 23 78 is bed
1. 5,5 duble
2. 5,4 duble
3. 4,4 not to bed
4. 16 take 5 good
5. 16 take4 good
6. 15 take5 good
7. 15 take4 good
8. 14 take 5 good
9. 14 take 4 not to bad
