Forget the Invisible Deck, John Bannon's come out with an Invisible Card using a regular deck of bikes and one very clever gaff. 

Paint It Blank, by John Bannon looks like this: You ask your audience member to mentally select any card. (Genuine free choice - no equivoke, forcing, cleverly worded limitations or pre-show used). They just think of one card. 

After performing the magical gesture of your choice, you let your spectator know that you've caused their card to become invisible. It's unlikely they believe you, but you insist it's true. You mime taking their "invisible" card from the deck and slide it between the two jokers. Instantly a real blank card visually appears between the two jokers. You place the blank card into the spectator's hands, and it prints itself into their thought of card. 

And it's totally examinable. 

Remember:

• Self working
• No sleights
• No forces
• No stacks
• No equivoke
• No off by one

and

• No reset

All you need is a regular deck of bikes and one gaff card (which is included)

This is ideal for workers - there's no reset and no table is needed.
