Bulbapedia gives plenty of useful in-game stuff you might need to know like what breeds with what for egg moves. It's quite in-depth in that aspect. If there is an easy way to link to other Dex, it could be useful. It isn't a necessary need but it's good to know where to get information from :)
Thanks for the reply! Well, some of the analyses did mention the more important illegal movesets, but I get what you mean. The page with the moves the Pokemon learn isn't particularly useful now since it doesn't even have all the moves it learns and also what you said.
Veekun wasn't brought up yet when I wrote my post, so I saw no reason to link to Serebii or other Dex since it's not really worth the effort to do so. But yeah bad analogy there my bad :x Thanks for your time! :)
