MacKenzie will be performing next week at the Manchester Publicity Association.
But it turns out he's not trying to be the new Paul Daniels. Instead, the cards will form part of his attack on the radio measurement body Rajar.
The former editor of The Sun will be handling out a pack of cards to each member of the audience to illustrate his concerns over Rajar's diary measuring system, part of which involves flashing 38 cards in front of listeners to jog their memories over which stations they might have listened to.
MacKenzie's deck is dealt with the message: "Rajar does not have to resort to Blue Peter-style bits of cards, stickers and pencils ... It's called modern technology. Don't be frightened. It works."
