Gus, I think I lost you on this a little bit... Please allow me to talk of the typical "lay of the land". In any casino, particularly when the players touch the cards, these cards are taken out of play eventually and brand new cards, fresh out of the box are introduced to the game.
Something I observed in a Native American casino (I can't recall which, either in Arizona or New Mexico) I observed them making all preparations to open up a new table for the day. Whereas in AC they change out the cards once a day for new cards every 24 hour period and also utilize new cards right out of the box to start a game with that has been previously closed, they did it a little "different". The pit strolled up to the table with cards that had been previously used, put back into the boxes, stored in a plastic bag and then pulled right back out to use again at a later time! They don't put new cards into play and simply reuse the same ol' cards, day after day!
This leaves lots of possibilites for "less than scrupulous" practices on the part of the casino to say the least.
