Armaldo

Armaldo sets itself apart from other Pokemon in the PU metagame with its access to Rapid Spin. It also has a very high base 125 Attack and access to Knock Off, allowing it to cripple spinblockers such as Misdreavus and Dusknoir. On top of that, Armaldo has access to Swift Swim, making it a threatening Swords Dance sweeper in rain. However, Armaldo's Rock / Bug typing leaves it vulnerable to common attacking types such as Water and Rock, although it does allow it to check Normal-types such as Stoutland and Ursaring. It is also very slow, making it easy for faster Pokemon such as Floatzel to take advantage of. Armaldo lacks the space in its moveslot to fit moves such as Toxic, Aqua Tail, and Stealth Rock, which holds it back from having extra utility. Armaldo is also vulnerable to every form of entry hazards, making it difficult for it to consistently remove them with Rapid Spin, which is a pretty big flaw for a Pokemon that is supposed to remove entry hazards as reliably as possible.
