Beartic

Beartic has a good Attack stat and very usable bulk, along with an excellent Ice typing that gives it powerful STAB Ice-type attacks to abuse. However, that typing is a double-edged sword; although it's good offensively, it brings with it many weaknesses that severely undermine Beartic's otherwise quite decent bulk, and its mediocre Speed ensures that it's only useful under Tailwind or Trick Room. Its STAB Icicle Crash does huge damage to a multitude of common Pokemon in VGC 2011, but its movepool is quite limited outside of that. While its low Speed, terrible movepool, and many weaknesses may make it difficult to use, its powerful physical Ice-type STAB is unique in the tier, this making it a viable choice for a Trick Room or Tailwind attacker.
