Use a shared external source of randomness, like one of the shortwave “numbers stations”, to seed an agreed upon algorithm that simulates shuffling a deck and dispensing the cards. You’re running the same code on the same data, so you could show the cards you had seen after each hand to confirm everyone is in sync.





If you paint over the reporting marks (“CRYX” and the number), it requires them to patch the data back on much more quickly than if you just paint other parts of the car.
