My feedback:
1. I don't like the name of the deck. "Epic" is such an overused modern term. I like the theme, but "Epic Japan Deck" is very lame. "Heroes of History: Japan", just off the top of my head, sounds much better. It's your campaign, though, and other people may like the name.
2. Although I normally don't like 1-way backs, I think that this one is very nice. I like it.
3. These court cards are magnificent. Absolutely great. Great borders, great artwork, great execution.
4. The number cards are the opposite. Very bad. There is way too much going on. The borders are fine, even good, because they're more minimalist than the courts. I like that.
5. Another abnormality; having 4 different colored suits, also looks good in this deck.
6. The jokers are fantastic. More really great artwork.
7. The aces are not good. The different watermark from the number cards also bothers me a lot.
8. The tuck case is another good part of this project. I like it.
9. The price seems a tad high for an LPCC deck, but it isn't too high (for me). A good printer choice for the borders that this design has.
10. I just noticed the stretch goal of Gold Perfect Foil...
There is a LOT to like about this. I can't back it right now, though, because for me the number cards are just very bad... Even if I use these just for euchre, the aces are so bad that I wouldn't.
