And the moves....

Take Down
Aerial Ace
Leaf Blade

I don't have experience with this Pokemon, so I can't decide. Since it's shiny, please, don't tell me to get a new one.

Okay, please get a new one.

Leafeon @ Leftovers

EV's: 252 HP / 20 Def / 236 Spe
Impish Nature (+Def, -SAtk)

- Yawn. Edit: There's the SD Set, but I prefer the Wish Set.

Yes, thanks, but any ideas WITHOUT getting a new one?

Nope. There's no Set including a Naughty Nature. So if you want one without getting a new one, you'll have to make up Novelty.
