Dragonair

Dragonair boasts an incredible typing for play in the RU tier, which, when combined with its great Eviolite-boosted defenses, amazing abilities, and solid movepool, makes it a great candidate for a spot on offensive balanced and semistall teams. Marvel Scale and Shed Skin are what make Dragonair so potent, as they both immensely aid in setting up. Dragonair's niche in RU is as a bulky Dragon Dance sweeper; straight offensive sets are largely outclassed by Druddigon, which features amazing power without setup, and Fraxure, which is only marginally slower but much more powerful after a single boost. Dragonair's bulky Dragon Dance set is amazing though, with its only major weakness coming from its tendency to get ruined by critical hits. If you're looking for a fun Pokemon to use and can provide Magneton support to remove Steel-types, Dragonair should not disappoint.
