GUYS
Talonflame has Gale Wings, right? Right, duh.

Is a complete Support set viable for it? Something like

Talonflame @ Leftovers
Ability: Gale Wings
EVs: 252 HP / 4 Atk / 252 Spe
Jolly Nature
- Defog
- U-turn
- Tailwind
- Will-O-Wisp

No it isn't what Talonflame usually does, and yes it has x4 weakness to Stealth Rock, but Talonflame is one of the Only Pokemon with priority Defog - probably the only one. Talonflame also has priority Tailwind and even U-Turn that it can use to switch into a usually slow teammate that really appreciates Tailwind, like base 100s (looking at you Mega Gardevoir).

Will-O-Wisp can be used to burn TTar, Garchomp, and Rotom-W, all common switch-ins to Talonflame. It still can't touch Heatran but it can just U-Turn to something else that can deal with it.

Priority Defog could help Pokemon like Dragonite and Pokemon that usually carry a Focus Sash like Breloom, Terrakion, and even Bisharp.

What do you think? I'd like to hear some opinions on this
