I just watched the episode where Ash challenges Whitney for the first time. Out of the three Pokémon she used, only one was normal.
First she used a Nidorina, which is pure poison and to my knowledge always has been. Then she used Clefairy, who was normal when generation 2 came out, but is considered Fairy now. And then Miltank. 

I think in the gme she just uses Clefairy and Miltank.
