Invisible Miracle by German Dabat

Image from Murphy's Magic
You show a red deck of cards and leave it in plain sight. You hand the spectator a blue deck, and they can cut it as many times as they like. They choose either the top or bottom card and hide it in any pocket they want. Then, they hide another card in a different pocket and reverse one card in the deck.
Now, you reveal that you've predicted everything! Inside the red deck, there's one reversed card with a message written on its back. It reads: "Right pocket: 10 of Hearts, Left pocket: 4 of Spades." Finally, you turn over the reversed card and it matches the spectator's reversed card perfectly!
