The magician asks a spectator to selected a card from a regular deck, but don't look at the card yet. Next he shows 4 cards freely on the back (no funny counts) and turns them over. He shows that they are all the same card (King of Spades for example)!
However, when the selection is turned over an indifferent card shows up... (eight of heart for example).
The magician now magically changes one at the time his four "prediction" cards into the selected card. Fronts and backs are shown freely again! No funny counts.
You will receive special gimmicked (bicycle back) cards and an instruction DVD.
