What would it take to produce six selected cards as a card cube.
What would it take to have one or more of the cards signed?
Agreed that one viable approach is to have the card cube componant cards all be face inwards.
How many could be face outwards if the backs of the cards were singed instead of the faces.
Yeah, seems it might work as an extension of the old cop and fold stuff. Now it might be cop/folk/assemble.
Force and steal out six dupes, and spring the remaining cards violently into a hat, which has a card cube loaded into it, with the card backs facing outwards. Shake the cards in the hat.
Then start pulling cards out, as you do, you are folding them, widthwise, lengthwise, et cetera as you pull them out.
"Clumsy! I'm ruining these cards, they're getting all bent and folded!"
Drop them all over. After you've done as much damage as you have time for dump all the rest out, they'll be somewhat bent from the springing, and oh, yes, there's these cards formed into a perfect cube.
Which contains the selected cards. The implication being that you cleverly controlled and folded them in the process of dumping the cards out of the hat.
