Any evolutionary lines you'd shorten?

Yup, I'd cut Steenee out of the Bounsweet's evolutionary chain because Bounsweet is a Magikarp stage and doesn't need to evolve into Steenee, who is another Magikarp stage.
Also, Pansage/Pansear/Panpour: I'd increase their stats to 150% and cut their evolutions.

No Magnezone or Rypherior. Think Vanilite better off as 2.
