Your grammar is really not THAT bad-- like I said, you're doing a lot of things right. I just think you're getting a bit sloppy with some prose; watch your singular/plural subjects for instance. You're actually one of my favorite new contributors :)
Some content things I was going to fiddle with, a few key counters you are missing like Rotom-C and Poliwrath (both of which are better than something like Rotom H or Jolteon).
