JUSTIFICATION OF USING A JUMBO DECK
Because it smaller than the magician's hand, a normal-sized deck makes it possible to use sleight of hand techniques. Due to this being a mental experiment, I would like to avoid the possibility of using any sleight of hand techniques; therefore we will use a Jumbo deck.
