I'll just say, I only have a very vague idea of what's going on here. But maybe someone like that's the person you need to hear from.
You say the problem is "newbies" aren't getting involved.
I would say this is a result of the elitist attitude of this forum. Just reading around, it's constantly being mentinoned that this is "Only for people with extensive knowledge of competitive battling".
Which has two consequences. One, the new players don't feel they are welcome here. Secondly, they know that if they come to this place, there will only be "pro" players. They won't have motivation to fight, because they know their opponent's knowledge/skill far surpasses theirs.
Not to mention, even "normal" competitive battlers won't have any experience in the CAP metagame, and the regulars/those who have been there since the start will just win from pure experience in the environment. Most "Normal" competitive battlers simply won't bother because they're just so much more comfortable in the environment they're familiar with.
Now, I'm not saying it's a bad idea to make the point clear that this project is only for these highly advanced players... but it's made maybe too clear, and the standard is set too high. I know I took slight interest in a "Create-A-Pokemon Project" but when I casually looked into it, I got a real "get out unless you're super serious and pro" vibe.
Wouldn't know how to solve this, just voicing my thoughts. I really am not out for any motive except to give you insight from someone outside of this project.
And I'm not some fanboy trying to bring to life a creation from year 5, I'm genuinely interested in competitive battling and would be interested in ironing out what I consider some fundamental flaws.
Sure, I've been out of the game for a while, too much study and such to do, but I played competitive battling for a very long time and it's fairly cemented in my system.
One thing I was very impressed with in this project was the Mountaineering ability: First thing I thought when I saw a Bug/Ice Pokemon was "Too bad it gets destroyed by Stealth Rock", as is an unfortunate reaction to many pokemon with the wrong typing (Articuno for example). But that ability was a pleasant slap in the face to my prejudice.
I also like that you created moves to cover some physical/special power that certain types lack (the rock one in particular). And a usable Pokemon with Unaware. And a well thought out Rapid Spinner. Plus the art of these Pokemon is awesome =]
