I am a fan of Rapidash, but its not as powerful as some other Fire Types. It’s thing is that it runs really fast, which would make me think it has one of the highest speed stats in the game, but it’s not even the fastest Fire Type.. So I wanted to share my idea for a signature ability and have your opinion. “Fast Burn” – All Fire moves have Priority 1 and will go before any attack (including Extremespeed).

Well, minor point of description, what you’re actually saying is “all Fire moves have priority +3” – the reason Gale Wings doesn’t beat Extremespeed is because Extremespeed has +2 priority rather than just +1 like Quick Attack et al.  +3 would mean that Rapidash automatically outruns Extremespeed, Feint, Follow Me and Rage Powder, and can potentially outrun Fake Out, Endure, Wide Guard, Quick Guard, Crafty Shield and King’s Shield, but still loses to Protect. [EDIT: At the time of writing, Bulbapedia listed King’s Shield as +3. This is incorrect; it’s actually +4, which means you can ignore the rest of this paragraph.]  The big deal here is King’s Shield, because +3 priority on Fire moves would mean that Rapidash absolutely murders Aegislash (who’s not going to outrun her on a priority tie).  If you’re okay with that, fine – Aegislash could stand to be taken down a peg or two – if not, make it +2 and Rapidash can still outrun slower Pokémon using Extremespeed and faster Pokémon using lesser priority attacks.

Anyway.  What we’re getting here is the Fire equivalent to Talonflame’s priority Brave Bird, in the form of Flare Blitz, so it makes sense to compare the two (priority Will’o’Wisp is not nothing, but I feel like Flare Blitz is the big draw here).  Rapidash’s physical attack stat is significantly higher than Talonflame’s, though, which is worrying when you consider what a dangerous Pokémon Talonflame is, largely on the back of Gale Wings.  Their defences are similar, and Rapidash has less trouble with Stealth Rock but doesn’t get Earthquake immunity.  The main disadvantages are that Rapidash doesn’t have a second STAB attack, can only heal herself with Morning Sun, doesn’t have set-up moves (although Hypnosis could be interesting), and doesn’t have U-Turn.  She does have marginally better coverage with Megahorn, Wild Charge and potentially Drill Run through the Black and White 2 move tutors.  Another point is that Fire, unlike Flying, has no shortage of good special attacks, and while Rapidash prefers physical, her special attack stat is actually very similar to Talonflame’s attack, which means that bunging in Overheat to murder physical walls is a very real possibility.  I don’t think it really ruins any of the Pokémon that would otherwise counter you, but it will certainly make life more difficult for them.  Overall… it makes perfect sense in terms of Rapidash’s flavour that she should be the fastest of the Fire-types; she’s supposed to be a speed demon, and this certainly gives her that. She would certainly be dangerous, and I’m just generally wary of handing out anything that compares favourably, by any metric, to Talonflame’s Gale Wings, but she lacks some of the little extra tricks that help Talonflame to really shine like Swords Dance and priority Roost, so I don’t think we’re getting into broken territory here.
