Yup. If you can find a game with no strips and no more than 2 riffles in the shuffle, then you could probably manage this with a fair degree of accuracy and you'd only need one key card - no chance of a false key in a single deck game
. You could also probably manage to track as many aces as you could get a look at each round, not that you'd get to play them all but you'd get to play a worthwhile amount.
The real work in this game is finding that type of shuffle with a dealer who is accurate with their riffles. They do exist, but they are hard to find. After that it's pretty much plain sailing!
