Okay well the common Move Set I've seen for Talonflame is this:
Talonflame (M) @ Life Orb
Ability: Gale Wings
Nature: Adament/ Jolly
EV's: 252 Attack, 252 Speed, 4 Defence/ HP
- Flare Blitz
- Brave Bird
- Roost/ Swords Dance
Therefore I recommend any of the following Pokémon:
Regirock Rotom-H Rotom-W Tyrantrum
The reason I would recommend each of these Pokémon is because they all resist both Fire and Flying Type Moves.
Regirock has amazing Defence at 200! so it can easier counter Talonflame as it resists both it's Fire and Flying Type Moves. It can also set up Stealth Rocks which will reduce Talonflame's HP by 50% of it's Maximum every time it switches in.
Rotom-H resists both Fire and Flying Type Moves as well as the Bug Type U-turn. It can easily cripple Talonflame with a Thunderbolt. Not to mention it has Pain Split.
Rotom-W resists both Fire and Flying Type Moves. It should force out Talonflame with fear of a Hydro Pump or Thunderbolt.
Tyrantrum resists both Fire and Flying Type Moves and it also has access to Stealth Rock. It should easily OHKO Talonflame with Head Smash if it has the Rock Head Ability. You could even give it a Life Orb for extra power.
Mega Ampharos resists both Fire and Flying Type Moves since it is part Dragon. It will force out Talonflame with fear of a Thunderbolt with it's mighty 165 Special Attack! It even has the Ability Mold Breaker.
Hope I helped :)
