God, why are there so many physical sets?! I mean Lucario already has a higher special attack. Just sayin.... But yeah. So here's my set. It's a special set, if you haven't found out yet.
Evs: 252 Special Attack 252 Speed 4 HP
Item: Life Orb/ Focus Sash
Ability: Steadfast (Now don't criticize me for this. I've always like this one more. Gives you a speed boost. )
Calm Mind/ Nasty Plot- Depends whether you want to go full special sweeper, or balance things out a little. I went with Calm Mind.
Aura Sphere- STAB. Just a great move. Never misses too.
Dragon Pulse- Strong, Special move. Coverage for dragons.
Dark Pulse- Used to piss of Psychic and Ghost types with and unexpected Dark type move. I just love doing that! :3
Other options: Psychic- Covers other Fighting types and Poisons. Poison types will be so P.O.ed that they can't attack you, but you have a super-effective move.... If using this, replace Dragon Pulse.
Flash Cannon- STAB. Also great accuracy. Deals with pesky ice types such as Sheer Cold using Walreins. (And there goes your win-streak thanks to hax.... ) Again, replace Dragon Pulse if using this.
Well that's it. Rate well!
