ReinCardNation

Effect: A card is signed, one corner is torn off, you now fold the three-quarters of a card up and then unfold it again but pretend that you've actually ripped it up and fixed it. Finally you take the final piece and after a lot of fucking about you pretend to fix it back by rotating the card and palming a piece. Thankfully before anyone notices you've not done much magic you rip it all back up and vanish the bits.

Would probably fool prison inmates on crack.
