+hp/-def karla

I mean, that's pretty good IV's, really. Her defenses are already pretty low and she doesn't have a bane in Atk or Spd. She's sitting really nice at 35/40 offensive spread. That's really, really good for an attacker. Slap on L&D/Fury/Swift Sparrow/Brazen Atk/Spd/Darting Blow and you'll be good to go. Her kit works really well already, she just needs an A slot and you'll be good to go.
