Ultimate Invisible Deck (Double-Sided Blank) Magic Trick

The Ultimate Invisible Deck, perfected for the modern era.
The method is simple and can be learned in minutes.
No memorization or calculations required.
Suitable for close-up to stage performances.

However, the value of this product is not just in its simplicity or gimmick.
It makes sense, and the story is complete.
That is the Ultimate Invisible Deck.

Effect:
The magician introduces the Invisible Deck and has the spectator shuffle it in their imagination.
The spectator, with complete free will, chooses any card and announces its name aloud.
Then, they return the card to the invisible deck.

The deck is placed into an invisible case, and the magician then takes out an empty paper bag.
With their own hands, the spectator places the invisible deck into the paper bag.
At that moment, a real deck of cards appears inside the bag!
The card case that is taken out is a completely blank white box.
Inside are only cards that are blank on both the face and the back.
However, with one exception.
It is the single, genuine playing card that perfectly matches the card the spectator freely chose.
