Abomasnow

Abomasnow is a Pokemon that does not look great whatsoever on paper. Its awful defensive typing leaves it weak to some of the most common offensive typings in RU, such as Fire, Rock, and Fighting. Moreover outside of decent HP and mixed offensive stats, Abomasnow's stats are all mediocre. Despite these shortcomings, Abomasnow still remains a potent wallbreaker in this metagame. Though Abomasnow's typing is extremely poor defensively, it is stellar offensively. Abomasnow is able to take advantage of its ability Snow Warning by spamming Blizzard, which has 100% accuracy in hail, and use its Grass-type STAB moves to stop bulky Water-types from countering it. Furthermore, Abomasnow gets fantastic coverage outside of its STAB moves in either a Ground- or Fighting-type attack to hit Steel-types, as well as a priority STAB move in Ice Shard, which can be extremely helpful in certain situations. With proper team support, Abomasnow is extremely dangerous against balance teams thanks to the many opportunities it gets to punch holes into them, but without the proper support it can become dead weight.
