Zebra Code Prediction by Astor and Louis Black

Here's an amazing and very visual prediction effect. A special Zebra Card prediction is placed on the table at the beginning of the performance. From a shuffled deck, the spectator selects two cards. The magician now inserts the Zebra Card into a holder. Suddenly, there appears a very visual and magical appearance of the first card, followed by the second card - the predictions are correct, thanks to the Zebra Code!

Easy to do, and a miracle to behold!
