This. I also enjoy playing in the Create a Pokemon discussions and meta. They come up with some pretty hardcore pokemon that aren't utterly broken. One of my favourites is a mon which can use Sketch, but only once (Necturna), and there is a big fat dancing, sun bringing tree to help make Non Rain Weather actually useable (Jumbao).
They have 24 mon created and are making a trio of starters (along with all the limitations that brings: no megas, 515-535 BST, not to exceed or drop below the established starter norms, limited to one useable ability, FWG, etc.
