blanked imagination

So I joined a group on facebook of all places. sell your magic you dont use kinda deal.
I picked up a trick called void. Have someone pick a card, look at it, then hold the card. meanwhile you hand the deck to someone. long story short, the selected card turns blank and the whole deck is blank.
Yes this sounds somewhat like blizzard as well. But they all had something missing for me. They All USE Some sort of gimmick. So after watching a lot of reel magic magazine and talking to my cousin on the subject I figured out i gimmick less option.
Spectator shuffles the deck, sees the faces, picks one out.  next they sign the card and place it into their hand. the deck is boxed and handed to someone else. Grand finale is the signed card is now blank and deck is blank.
I tried it out and all I can say is I am amazed at how much you can get away with right under peoples noses. Tried it on a magician buddy which blew him away. Its another one of those...FULL BALLS tricks.
