Shadow - Alex, Wenzi & MS Magic

https://youtu.be/aRtOjYk8eME

From the genius mind of Alex

Effect:

The magician displays an envelope and a blank card, places the blank card inside the envelope, and has a spectator sign in the window of the envelope.

A card is chosen and signed, then vanishes from the deck. The signed card magically transforms into their selected card with their own signature!

• Easy to do
