I just posted the same comment on the KS project page. PCF is the Playing Card Forum, the official discussion board for 52plusJokers card collecting club...they are more vintage and antique card collectors here, but also many modern card collectors. FaceBook (FB) Group named: Playing Cards - Crowdfunding - Kickstarter.
Some other suggestions I would like to make:
1. TUCK BOX - I didn't see one on your project page, but this is extremely important to many collectors, especially since many don't open their decks. Features like embossing or foil are add-ons that can be obtained through stretch goals.
2. Back of Card - You might want to re-do the back of the cards as the text is not interesting (imho) and doesn't add to the design. Also, there is something missing...maybe add a border?
3. PRICING - 15 USD per deck (plus shipping for international) is quite high. You might want to lower the base price and separate shipping (charge it separately). The fact that you are using USPCC is probably part of the reason that your price point is so high and you might want to consider other printer options like Expert Playing Card Company (EPCC) and Legends Playing Card Company (LPCC) which might have lower costs.
4. REWARDS - You might want to offer some Early Birds as well as different tiers to include 1, 2, 3, 4, 6 and 12 decks as those are usually the standard quantities people like to order. You could also look into Dealer Coins and other things as an add-ons to help boost the amount raised, but be careful not to get too carried away and find yourself dealing with a lot of suppliers as there is more variables and thus more probability for problems/delays.
This site is a goldmine of knowledge for designers and I suggest you go through the Custom Deck Drafting Board to see what others are saying about the decks that have are on the boards. Continue this thread before you launch again and ask the members what they would like to see changed as well as for suggestions on improving the deck overall and thus the probability of getting funded. Nothing is guaranteed, but it will surely increase your chances.
Best of Luck and if you don't make your goal this time, I will definitely be backing again.
