I have a relevant replay if you're interested, but essentially whenever anyone brings out a talonflame you know they're going to use brave bird, so switch in to cofagrigus and talonflame's ability automatically becomes mummy instead of gale wings. Cofagrigus also has the bulk to take a hit from brave bird without dying right away.

so how many brave birds does the mummy survive though? I'm sure talon outspeeds it even without galewings. and if you switch after mummy takes effect, they will either switch or use another bravebird regardless, so you'd need to switch into something that can take another brave bird easily. which would be a rock type which would beat talonflame with or without mummy. worst case- you mummy yourself
