Cubone

Without a doubt, Cubone is valued almost entirely for a single trait: access to Thick Club. This unique item doubles its Attack stat with no penalty, making it an extremely dangerous force in the Little Cup metagame. In fact, with its signature item, Cubone can reach an Attack stat as high as 30, easily overpowering all Pokemon without a Choice Band. Cubone is not a one-trick pony either, as its phenomenal base Defense stat of 95 allows it to switch into physical attacks and even wall some attackers, although its typing isn't helping it much in that regard.

Cubone also has some other attributes that make it a great choice, such as its very impressive movepool and good offensive typing. Cubone's Ground typing does, however, leave it with three common weaknesses and few resistances. Overall, Cubone is usually a huge asset to any team that it works well on despite its minor restrictions.
