I'm diggin' the playing cards Idea. Minor suggestion though; Because of their supposed ties to the mystical and the basic meanings that sit behind them, perhaps a Tarot Deck? I think the idea of a secret city during the Renaissance seems like a good place to begin. As for substance, and I hope I caught your meaning correctly, but perhaps gauntlets, powered by electricity and producing a variety of effects or some such thing. A charged set of cards or book, revealing things about people's psyche or being used for an aggressive type of spell.
heh, the tarot deck, upon further research, actually gives me a lot more to work with (21 more infact) than a normal deck of cards does. So I actually will be using a tarot deck, thank you for the suggestion.
