After breeding for Recover on my Sableye, I started to think of different movesets, but I need some advice on a few things:

Stats:
HP Atk Def Spd SP. Atk SP. Def
50 75 75 50 65 65

First up is Personality, which to choose? The one I have now is Quiet (+Sp. Atk, -Spd), but I'm not sure how much use that'll be anymore, maybe a +Def would be more useful?

Next is, of course, the actual moveset. I was thinking about:
*Shadow Ball
*Toxic
*Mean Look
*Recover
Which is pretty straight-forward I guess, and I've heard Shadow Ball is based off Attack and not Special Attack (which is good for Sableye), but why then does it lower Special Defense? A +Def/+SP. Def would go well with this set, just for a bit more stability.

Then again Knock Off could replace Shadow Ball; I'll admit it's useful, but I like my Pokémon to have at least one decent attack to round them out.

Anyway, all advice is welcome, unless you're going to simply suggest replacing Sableye. Hold items would be also be Muchly appreciated!
