Misty had more fair battles that didn't involve weird, ridiculous anime physics or deus ex machina or whatever else you wanna call it, and they were more believable.
Blaziken- Strong, but not unbeatable, can be beat by one of her Water types.
Bulbasaur- Can probably take out one or two of them because of advantage, unless Misty finds a way to overcome it.
Skitty- With Assist DEM, can win, without DEM, will lose.
Eevee/Glaceon- Her moveset was terrible, Politoed or Corsola will win, maybe even Staryu.
Squirtle/Wartortle- With DEM, yes, without it, it loses.
Munchlax- Not bad, but not that amazing, either.
Bulbasaur/Venusaur- OU Gyarados and Flamethrower roast it.
Beautifly- Not that impressive, to be honest. Not a weakling, but still not impressive.
