I am currently working on a card change in which after a card is chosen by a spectator and lost in the deck I take out a card, show it, the card not being the right one, and then I perform a boomerang card throw and when I catch the card and turn it over it has changed into the chosen card.
I have a invented method already, but though it works, I do not really care for it, any suggestions on how I could do it differently?

Put up demo so we can see this in action

I actually have 2 methods, one is a simple double lift and the other involves a palmed card. And I do not have the resources to put up demos right now, vinny, but maybe I will in a few months. Thanks for your interest, Roy
