D. DECK (Online Instructions) by Dominique Duvivier

The magician thinks of a card, the spectator thinks of one as well.

The spectator's choice is completely free.

However, when the magician shows the rest of the deck, all the other cards are completely blank!

All the cards turn out to be blank, except for the two thought of cards!

Strong points:

• No roughing fluid.
• Easy to do.
• Several routines explained.
• Bicycle Rider Back cards printed by USPCC
• Online video instructions.
