Armaldo

Armaldo is a weird Pokemon, to put it bluntly. Its main niche is Rapid Spin, but its stat distribution and typing make it an extremely awkward candidate for this role. Speaking of its typing, Bug / Rock doesn't really do Armaldo any favors. While it leaves Armaldo with relatively few weaknesses in just Water, Rock, and Steel, it also only offers resistances to Poison and Normal. Not only that, but Armaldo is also weak to Stealth Rock and takes damage from Spikes and Toxic Spikes, which sucks for a Pokemon whose main role and niche is spinning away said hazards. However, its typing does give it a neutrality to most common attacking types that other spinners are weak to, including Fighting, Ground, Fire, and Flying. Armaldo's main perks as a spinner are its gigantic base 125 Attack stat and deadly STAB combination. It also has a nice base 100 Defense stat, which makes it a formidable tank. It's too bad that its huge Attack stat and awesome offensive STAB combination are wasted on such a slow Pokemon. All in all, Armaldo is probably the worst spinner worth considering in RU; however, it provides a couple of unique niches, so it's still worth a look into if you want to try something different.
