Err, lets say i manage to obtain a duplicate of an audience selection with his signature on it.. then how can i fully exploit it.. i tot of doing teleportation of that card that looks impossible.. u get wat i mean.. ;) or can end with a torn and transpo which is definitely easy.. so u guys hav any novel ideas that can be suggested?thx.

That really depends on when you get your duplicate. If you had your duplicate the day before, there will be so many ways of revealing it. Signed card in Lemon, in sealed envelope, in someone else's pocket, in your shoe(although there is a way to do it even without the duplicate), and anywhere you can ever imagine, you just have to plant it there.

If you only obtained your duplicate while performing, your choices of your card revelation will be limited compared to you getting the duplicate beforehand. Torn and restored signed card will be a great ending. If you have a helper you can probably do a card to flower vase or card through window.

Hope this helps!
