I have a new mentalist card effect. Before the effect begins the mentalist gives an envelope to the spectator to hold onto during the performance ... The mentalist then shows a deck of 52 playing cards, on the back of each card has a written name. 52 cards 52 different names. The cards are shuffled then the mentalist asks the spectator to name any card out loud . " the jack of diamonds " on the back of the jack of diamonds the name Jeff is written .... "Please open the envelope you're not going to beilve this ..." The envelope is opened by the spectator it reveals a name written on the peice of paper ... Jeff The cards and envelope are fully examianble, any card can be named!!!!
