I've been using a core of Staraptor+Talonflame+Hawlucha. Gotta say, its pretty impressive. You can just lure out the flying resists with raptor (who can still dent them with Brave Bird/CC), and sweep with one of the other two. my hawlucha set is -
Lucha
Flying Gem
252 Atk/252 Spe Adamant
Unburden
- SD
- Acrobatics
- HJK
- Encore
Encore is usually to create setup opportunities. SD helps with Lucha's average-at-best Attack stat, but you still wont need it all the time due to the power and coverage of its STABs.
I'm really hoping 'Raptor,TFlame and Lucha end up in UU, I'm gonna spam the hell out of these three :D
I can see why the Staraptor and Hawlucha core would work, since Staraptor has some serious cohones offensively and Hawlucha has that great typing, superior speed and powerful STAB fighting move to potentially break through the few Pokemon Staraptor struggles with (Metagross, Rhyperior, Bronzong, Skarmory), so they could soften up each other's checks and counters.
Talonflame is another story though, IMO. It's fast but its offensive AND defensive stats suck, not to mention its 4x weakness to SR and lack of any way to break through rock types besides the mediocre Steel Wing. It also relies on setting up which is pretty difficult when you take 50% damage just entering and will most likely have to endure another attack on your 70/70/70 defenses to get the SD boost. It's SD-boosted power and Gale Wing ability might keep it out of NU, but I don't see it being above RU unless the metagame becomes very susceptible to its STAB combo. As a sort of analogy, let me direct you to Weavile, who has similar speed, an (arguably) superior offensive typing, lesser weakness to SR, similar defenses, massively superior offenses, better coverage (now that it doesn't need fighting moves to break through steel types), and reliance on Swords Dance, along with a great STAB priority move that was supereffective against the most threatening typing in OU last gen. Even with all these great traits,
and in a dragon-dominated metagame, it was still only scraping by in UU. For everything Talonflame has going for it, it has a lot of negatives and I don't see it really being as good as some people are making it out to be.
Anyway, back to Hawlucha, yeah I can see why its STAB moves could mitigate its mediocre attack stat, but I'm still not convinced he's really OU material. If priority turns out to be less common than last generation then he could become a force as a cleaner or wallbreaker, but with all the massively quick and strong mega evolutions, more powerful offensive Pokemon and the very existence of incredibly fast Pokemon that are not only popular OU choices but can also easily KO it (most notably Alakazam and Jolteon) - and of course the infamous Aegislash who laughs at everything it tries to do except Encore (even a +6 Brave Bird is useless since King Shield weakens it and it has supereme bulk and resistance), while setting up its own SD and kicking its teeth in with priority Shadow Sneak. All-in-all, there might be too much getting in the way of Hawlucha for it to be OU.
