Effect Any card is freely named. It is the only card marked with an 'X'. Notes: Only one deck is used. Any card can be named, even a Joker. No re-setting required. Always ready to go. It really is a hand-drawn 'X', drawn with a permanent marker. It's a new, modern twist on the Invisible Deck trick. This is what the backs of all the cards look like. This trick uses the 52 on 1 Deck. But I've tricked it out to make this super-easy to do. Note: 50% of the time, the regular face of the card is marked with a large 'X'. The other times, the mini-image on the back of the card is marked with an 'X'. But, either way, the named card is the only one with an 'X'!!!!
