Pokémon X and Y Playthrough Discussion

I read somewhere (I think Bulbapedia) that there is no Fairy type HP and that the formula used to calculate type from gens 3 to 5 is still being used.

Just found out my shiny Delphox has the rare Dark type HP...which won't help it much unless it were facing another Delphox or Victini.

Shadow ball would probably be the better choice in regards to most other psychic types anyhow. She can learn it via TM.
