Mentalism Routine in Progress... Thoughts?

Hey everyone, I've been working on putting together a mentalism act to perform this holiday season. Right now, it's made up of two effects. Cheers!

1st: "Divination" of a Freely Thought-Of Card.

Here's how the effect plays out: the magician says something like, "Do you believe I can know what you're thinking, even before you've fully formed the thought?" You're probably thinking, "No way!" But sometimes, it's actually possible. To demonstrate, the magician writes a prediction on a piece of paper. This paper remains in plain sight until the end of the effect. A spectator from the audience is asked to think of any card from a poker deck. Once they have a card in mind, the magician brings out a deck, explaining that it's not just any deck, but a very special one—not because of the faces, but because of the backs. Each card has a different name on its back. (For example, the Three of Spades is named Raul, the King of Clubs is named Alejandro, the Eight of Hearts is named Maria. This is done with all the cards, so each one has a unique name.) After displaying the cards this way, the spectator is asked to name, out loud, the card they've been thinking of since the beginning. Let's say they name the Two of Spades. The magician then searches for that card, emphasizing that it was a freely thought-of card and that he, as the magician, couldn't possibly have known what it would be. Once the card is found, the spectator is asked to open the paper that has been on the table the whole time. The magician stresses that the prediction was written long before they even thought of their card, and the spectator confirms this. In that tense moment, another spectator reads what's written on the paper: "Thank you for choosing SAMUEL." The Two of Spades is then turned over, revealing it's the only card named Samuel.

2nd: Impossible Divination. (My own invented title for the effect)

I hope I'm explaining this well without giving too much away. This is an effect from Juan Tamariz's Mentalism Seminar at El Escorial from many years ago. Following up on the patter from the previous effect, we can then segue into saying that, yes, it truly is possible to know a person's thoughts. Here's what the audience sees: A spectator signs a piece of paper from a notepad to ensure it can't be tampered with or switched by the magician. The illusionist then addresses the audience, asking each person to simply think of *any* three-digit number. The spectator holding the signed paper hands it to another spectator. This person writes their thought-of number in the top-left corner. This process is repeated two more times, resulting in three three-digit numbers, stacked one below the other. Once complete, the paper is returned to the magician, who then shows it to the spectator who initially signed it. Magician: "Is that your signature?" Spectator: "Yes." The person is then instructed to total the three thought-of numbers on the back of the paper. While they do the addition, the magician stresses that these were three numbers completely unknown to him—impossible for him to know what their numbers were (the magician was facing away the entire time). Once the spectator finishes the sum, they're asked to display the final result clearly (the magician is still facing away) and then tear the paper into tiny pieces. The magician turns around, as there's nothing left to see, takes the pieces, and burns them in an ashtray. The illusionist then comments that there's still information left within what used to be the pieces. He only needs to gather the remaining ashes and rub them onto a blank paper. Slowly, numbers begin to appear on the sheet, eventually forming and revealing the final total.
