Moody is banned, how dare you to question Smogon tiers?
Anyway Protect, Substitute, Frost Breath and Rest or Taunt. Ice Beam or Crunch for the physical version is fine too.
Octillery does better as Moody user, Bibarel too since those can use Dive and Dig for extra boosts, take care of water absorbing abilities of the enemy team first.
