Well, I perform with a deck with signed cards in it. But just on a few of them, because my decks get worn out before even close to all the cards are signed. I don't really mind, to be honest. I wouldn't have signed cards in the deck if I had an actual gig, though.
I don't mind giving cards out, I just don't do it every time people sign the cards. And I don't "force it on them", I only give it to them if they ask for it.
