>Pokemon that nobody uses in competitiveThe Pokémon you

Poison is resistant to fairy.
Steel AND poison are super effective against fairy.
Varoom is Steel/Poison type.
It is not Gardevoir, Hatterene, Sylveon, Mimikyu nor Lucario.
Revavroom is not popular at all among fans, not used in competitive and it's a very anti-fairy type (not cutesy) design.
