Along with it, there will be a sleeve for the 'box' (which will actually be a metal tin, designed to look like a sarcophagus/vault) for Kickstarter backers. KS backers will also get a bonus set of 10 cards.
Otherwise, the stretch goals--other extra cards, upgraded bits, etc, will all be available in the regular game...so those backers deserve thanks for helping upgrade the components of the game in general.
Speaking of that--the story cards for the game will be extra-large, the equivalent of "Tarot" cards while the Battle deck will be Poker sized.
The Tarot-sized cards will really show off the art, and just as importantly, will allow us to put bigger icons on those cards, making it easier for people with crappy vision...not to mention making the art bigger (and therefore much cooler)!!!
