The disappearance of a"FAIRY"

That has nothing to do with this game. The devs have no control over it. Fairy is gone and won't come back.

On a side note, why do so many people misspell "standard" as "standart?"

Fairy was removed and put into psychic type for balancing reasons. I don't know exactly what those reasons are, I know that Pokemon Company likes to randomly change Pokemon types in PTCG, ones that I remember are Poison types being put from Psychic to Dark, Fairies being put from their own type to Psychic, and such.
