>>19454840A gale wings ban is pretty reasonable and allows the types that Talonflame hits hardest a few more options to hit the bird hard or cripple it before it does too much. Your own priority now becomes a valid option, trick room works against it, holy shit you can even paralyze it or set up your own speed buffs. Personally I'd be more worried about scarfed or banded Staraptor turning up than a Talonflame, if I knew it was running flame body over gale wings.
Talonflame without priority is far less of a threat than many other common high power mons that see usage in teams here.
