Hail isn't being officially tested.

Answer 2

Nope, NU isn't testing Hail, brah. It's IN NU. Zebraiken doesn't appreciate quickbanning. :P

Ubers: Evasion Clause
OU: Previously tested Genesect, Kyurem-B and Garchomp.
UU: Previously tested Hail, which led to the unbanning of Hail in the lower tiers.
RU: Hail. Stupid quickbanners xD
NU: Previously tested Braviary.
LC: Nothing.

Yeah, they just forgot to remove that. They usually remove it after 2 weeks or so.
