I feel like you guys might be taking this the wrong direction.
Suicide Lead Talonflame @ Choice Band
Gale Wings, Adamant Nature
4 HP, 252 Atk, 252 Spe
Brave Bird
Flare Blitz
Steel Wing
U-Turn
What Talonflame has over almost every other Pokemon right now is a base speed of at least 120, and priority. This means that Talonflame's Flying attacks can outrun every Prankster user in the game. What this set aims to do, then, is to crash into the opponent, repeatedly, and go down with a blaze of glory. Flying and Fire are horrific defensively, but in an offensive capacity, it provides almost perfect coverage. With Steel Wing thrown in as well, the only Pokemon who resists every single move is our old friend Heatran. U-Turn provides a way to scout, or switch out without losing momentum.
And my take on the Mixed Attacker set...
Mixed Attacker @ Fire Gem/Flying Gem
Gale Wings, Lonely/Mild Nature
252 Atk, 4 SpAtk, 252 Spe
Overheat (TM 50)
Acrobatics
Steel Wing/Flare Blitz
U-Turn
Similar to the last set, but trading out pure kamikaze power for bouncing in and out, hitting with a surprising amount of power at remarkable speed. Overheat is the reason to go mixed, as lacking a proper way to deal with the typing, many opponents will switch to a physical wall. Lonely nature and a Flying Gem provides more OOMPH for the physical attacks, but if you want the Overheat to have that extra bit of surprise power, go with a Mild nature and a Fire Gem instead. -Def is chosen, as most of the types that Talonflame will want to switch into are either primarily special (Grass, Fire), or Ground. A Rock attack is going to OHKO Talonflame no matter what, so Defense isn't worth the investment. U-Turn is almost necessary with Overheat to bounce out and back in later. The choice of Steel Wing or Flare Blitz comes down to either reliability or coverage.
