If the casino cuts so much off the back you can try using the back card to play. Practice cutting half a deck, if that's their minimum, count the cards until the back card is coming, then bet accordingly. If the back card was an ace, play 3 or 4 boxes with the first and last minimum, middle hands big to collect the ace.
If the back card is small its even better, play the boxes the same but time it to give the 5 or 6 to the dealer.
I assume their shuffle is too random for shuffle tracking or ace tracking???
