A Most Unusual Predicament With Regards to Hole Carding Edge/ No Edge

There exists a game where I can determine the following by simply looking at the decks in the shoe.

By looking at the cards I know if the cards are in one of two categories by looking over at the cards in shoe. I can also quickly determine if the dealer's face down card is in category one or if it's part of category two.


Group One cards contain the following cards each time.

Card Value, Number of Cards

2s 5
3s 12
4s 7
5s 7
6s 8
7s 7
8s 7
9s 11
10s 9
Js 9
Qs 10
Ks 9
Aces 10

Group Two contains the following cards each time.

2s 12
3s 8
4s 10
5s 12
6s 15
7s 13
8s 11
9s 13
10s 13
Js 10
Qs 7
Ks 10
Aces 10


If these cards were in use in BJ, then what would happen to the house edge.
Yes, there is an unusual number of cards, something less than five decks.
