I honestly believe that the simple colour change is one of the most powerful effects performed in magic. I have taken my love for colour changes and applied it to a classic in magic, Cards Across.
When you purchase the Doppler shift you will receive detailed instructions on how to perform the piece and also how to make up a set from scratch. High quality original drawings by Nikola Arkane that will take you step by step through the process of this piece. And finally the cards required to perform the piece.
*The silks are used in my own interpretation of this piece and not a requirement to perform the effect.*
