Talonflame could be a useful utility counter for teams centered around Sticky Web. Two Pokemon with Contrary, Serperior and Malamar, actually get a speed boost from the hazard and potentially become very frustrating sweepers to deal with once they start ratcheting up their attack stats.
Serperior is demolished by either priority Acrobatics or Brave Bird, regardless of how fast it is. It also 4x resists Leaf Storm, giving an easy switch in.
Talonflame has precisely the right speed to outspeed Malamar even after it gets a speed boost, as long as it has equal speed EVs. For instance, Talonflame with 252 speed EVs and a neutral nature has 359 speed, Malamar with the same EVs and a boost has 358. Talonflame resists the obvious Superpower on the switch in and can deal a ton of damage with a x4 effective U-turn.
