YEEESS!! HAWLUCHA! This lil' fella is one of my favourite Pokes! I used one during my playthrough of X, and it has served me well competitively since.
+Incredible Speed at 118. You outspeed Gengar, Infernape, Scarf Magnezone and even 172 Speed Crobat to name just a few.
+Flying/Fighting is an incredible offensive typing, even better than last week's Rock/Ground. Only a tiny, tiny pool of Pokemon like Zapdos resist both.
+It has a very nice all-around movepool, with Acrobatics, High Jump Kick, Fire Punch, Swords Dance, Taunt and even Baton Pass (trust me, it's hilarious when it works!)
+It has two great abilities in Limber and Unburden.
+92 Base attack is certainly decent enough to work.
-Whilst it may be quite offensively potent, it's.. pretty bad defensively. 78/77/63 means that it really cant take many hits at all.
-Likewise, Flying/Fighting isn't exactly brilliant defensively. Not awful, but you are left with a few very annoying weaknesses to Electric and Fairy.
-Despite its great offensive typing and coverage, you are still walled by some threats like (Mega)Slowbro, Doublade and Zapdos (though the issue of Zapdos is somewhat remedied by Stone Edge.)
-Whilst 92 base Attack is good, it doesn't exactly hit like a truck when compared to stuff like Breloom or MegaZard X. You need SD to effectively sweep.
Is it a plane?
-Swords Dance

Hasty Nature
Ok, first of all, as a disclaimer, this set is a huge gimmick, as well as being incredibly convoluted to explain. It doesn't always work, but when it does, it's utterly hilarious, and can easily win games. Basically, the idea is that you lead off with it, then look at what your foe leads off with. If it's something like Forretress, Skarmory or Garchomp that basically always carries an entry hazard in a lead position, then you Taunt them (if you have it.) If not, you just go for Swords Dance- once you've Taunted them, you should also Swords Dance. You endure at least one hit due to the Focus Sash, which hopefully breaks the Sash and activates your Unburden for a huge Speed boost, then you can try to damage their team with either HJK or Acrobatics, but preferably, you try to get a safe opportunity to Baton Pass off you Swords Dance boosts to something really scary like Infernape of Terrakion. Once you have an SD boost onto a Terrakion, Infernape or something like that, your opponent has basically lost. Another perk to this set is that if you lead off, your opponent switches in Talonflame or Crobat, and you SD on the switch, then you actually beat them- they Brave Bird you, bringing you down to your Sash, but that discards your item and brings Acrobatics up to 110 Base Power, meaning that you can then thwack them with a +2 Acrobatics for an OHKO! The EVs make you as fast and strong as you can be, whilst a Hasty nature helps with this whilst also making your defenses lower so that it is more likely that a hit brings you down to your Sash. The Ability was already covered. I'll say again- this is not, I repeat, NOT its best set, nor is it very reliable. Really, if you use it, you are taking a huge gamble, but one which can pay off enormously, and makes for an enormously fun and enjoyable set to use.
