Cubone

When holding its signature item, Thick Club, Cubone reaches 28 Attack without a positive nature. This, paired up with its wide array of coverage, and its signature move Bonemerang, which allows Cubone to break through the opponent's Focus Sash, Substitute, and Sturdy, makes Cubone one of the strongest attackers in Little Cup. Cubone also has very good physical bulk without Eviolite. However, all these positive traits are balanced out because Cubone is very slow, doesn't have a very good ability, and it has low special bulk. Cubone also requires support from Sticky Web, Trick Room, or Baton Pass to work properly. Lastly, the presence of Knock Off heavily hinders Cubone's sweeping capabilities because it needs its item to truly shine. Regardless of all this, with a bit a bit of support, Cubone could become an excellent sweeper for your team.
