I already said this in #haxmons, but I might as well let people know. If you really hate Talonflame, there are some counters no doubt, though they may seem a bit obscure at first glance. Let's take a look at Mega-Tyranitar.
252+ Atk Choice Band Talonflame Brave Bird vs. 0 HP / 0 Def Mega Tyranitar on a critical hit: 124-147 (36.3 - 43.1%) -- guaranteed 3HKO
that's without bulk investment, now let's take a look at this:
252+ Atk Choice Band Talonflame Brave Bird vs. 252 HP / 252+ Def Mega Tyranitar on a critical hit: 95-112 (23.5 - 27.7%) -- 83.5% chance to 4HKO
lol?
and what can Tyranitar do back?
0 SpA Mega Tyranitar Ancient Power vs. 0 HP / 0 SpD Talonflame on a critical hit: 508-600 (171 - 202%) -- guaranteed OHKO
Now Mega-Tyranitar may seem bad, and not viable because of it's speed, but that is not the case. It's not that much slower than some existing threats like Kabutops and Dragonite. It's ability makes Excadrill an incredibly fast, powerful force allowing Excadrill to not only check Talonflame as well, but also dish out powerful, fast iron heads while resisting Extremespeed and Fake Out, very common in this meta. Mega-Tyranitar itself gets a ton of moves it can utilize very well in this meta: Body Slam, Dark Pulse, Fire Punch, Flamethrower, Ice Beam, Ice Punch, Ancientpower, Iron Head, Pursuit, Thunder Punch, Thunderbolt, Bite, Water Pulse and much more.
