Modest Nature (+SAtk, -Atk)
Just an awesome Pokemon. To be able to perform just as well if not better in LC as your evolution performs in the actual metagame isn't uncommon, except when your higher evolution is a top OU. Toxic will slowly sap away the foes will to live, and boost Hex up. Surf provides STAB, and since you'll be poisoning the foe, there is no need to use Scald. And of course, Recover for healing. Frillish has a solid typing and great defenses with Eviolite, reaching 22 HP, 21 Def, and 27 Sp Def, all while having a respectable 15 Sp Attack. And you can always fit it in on a Trick Room team, of course giving a Speed hindering nature.
