Both the weather abilities Drought and Drizzle are banned on mons under the OU tier (not including in OU, where they are allowed), meaning ninetales isn't able to use it in NU; this is because they were deemed too overbearing for these tiers to handle. As a nasty plot user, it has an alright niche, but compared to the other fire types in our tier (Pyroar, Charizard, Magmortar, etc.) it has a hard time actually standing out.
