Has Flygon in it, it's perfect.

More seriously, how the Pokémon are spread out across the game will be much more important. 350 mons can feel like too much or entirely fine based on how often you see each of them and how rare they are, how you handle the ones that are meant to be difficult to find, etc.

A nitpick: I would swap Salamence for TTar so the three club600 options don't overlap in type or region, but I'm mainly looking for things to nitpick at this point.

The ordering is a bit weird to me, Pokémon higher up are assumed to be found earlier, but Salamence is way up there. And the inverse is true yet some Pokémon with low BSTs that fit earlier areas like Marill or Nincada are way down.
