i created an effect where a spec picks a card, and signs it, then returns it to the deck. i take a different card that isnt theres , rip out the corner, blow on it and it changes to the corner of theyre card. part of the signature is still visible. so theres the corner of there card and the 3/4 of the previous card, AND THEY FIT TOGETHER PERFECTLY. then i grab the corner and restore it to the previous card. now that theres a crease, i visually remove it just by waving my hand over it. it LOOKS like theres a crease ont he card, but when they rub it, NOTHING... i then lay the card back on the deck, place my hand over it, then with a puff of smoke, the weird restored card changes into their previously selected and signed card....
