I'm use to filtering critiques, but the advice given were things that were niggling at the back of mind, so it really helped pulling in the trigger.
The indices and spot cards will take a little more time, but let me know what you guys think of the pips: are they still too abstract? I want the cards to be fun, yet playable 
The 10 cards are work in progress...
It's a big step forward in functionality.
Now, you have to remember something. In the States, Canada and much of the rest of the world, the majority of the people who will go for this deck will be children, with the next-largest category being female "kawaii" collectors. The deck's a bit costly for children, so you need to focus on marketing to the kawaii community. Third-largest would be people who love and/or own pug dogs, but I think that's a relatively small market to target in comparison - a lot of work to reach for a relatively small return on your efforts.
Some magicians may take note, particularly those who perform for children, but many find it simpler to just use the over-the-counter stuff from your local chain-store pharmacy or big-box retailer - especially when you factor in that more gaff cards and decks are made in the Bicycle Rider Back design than all others combined. I see you're using a modified Maiden Back design - I actually like Maiden Backs (they were designed as a replacement for the Rider Backs for magicians wanting to edit the back design), but yours are adequately different that they bear just a passing resemblance to actual Maiden Backs.
Simply put - many of the collectors here will not care for your deck, except perhaps those who absolutely must own all decks with the Bicycle brand name on them - they may not even like it, but out of their desire for completeness of their collection, they will feel an obligation to get at least one or two packs. But that doesn't mean that you shouldn't make it. It just means you have to market heavily in areas where you're less likely to find traditional playing card collectors and more likely to find people who love all things cute and cuddly. Websites where people (women in particular) enjoy talking about shoujo, bishonen or yaoi anime and manga would be a good place to start.
And in case you're not familiar with the Japanese terms:
kawaii = cute, but to a more extreme level in some cases - sort of like "hypercute", if such a word was real
shoujo = literally, "girl"; used to refer to stories written to appeal to girls and/or young women (this is sometimes spelled "shojo" in English, but the first "o" sound is longer than the second; it also sometimes appears with a bar above the first "o")
bishonen = "beautiful boy"; used to refer to stories (usually shoujo) with unusually attractive male characters
yaoi = masculine form of "gay"; refers to stories (usually bishonen) where the male characters become romantically involved or close enough to it through the use of sexual tension in the storyline.
anime = "animation"; used outside of Japan often to refer exclusively to Japanese animation.
manga = "comics"; used outside of Japan often to refer exclusively to comics drawn in a Japanese style, sometimes even when they aren't of Japanese origin.
