Once again, Mickael Chatelain offers us an incredible effect, an impossible one!

So impossible that we simply call it this impossible effect by Mickael Chatelain.

Imagine the following scene, friends...

Take a small envelope out of your pocket labeled "PREDICTION". Place it in a prominent spot or even hand it to a spectator—it's just an envelope.

Now take out your deck of cards. Show the faces and backs; it's a fully mixed deck. Spread the cards and invite a spectator to freely choose one.

Have them sign a sticker, peel it off, and place it firmly on their selected card. The signature is actually affixed to the chosen card—no switches, no sleights. You show the signed card clearly, then return it into the spread and display it again for full confirmation.

Now the impossible happens: the very same signed card is found inside the prediction envelope that has been visible from the start. The spectator's signature on the sticker proves it beyond doubt.

This presentation creates a strong, clean, close-up prediction effect that will leave spectators stunned. Perfect for walk-around and parlor work, it reads like genuine magic and sticks in the audience's memory.

Remember these highlights points:

• Easy to perform
• No sleight-heavy manipulation required
• Envelope can remain in view or in a spectator's hand
• Reset in seconds
• Several performance variations explained
• Clean presentation — the chosen card is openly displayed until the final revelation
