Lunatone

Lunatone has an uncommon Rock / Psychic typing, which gives it resistances to types such as Normal and Flying. It also has a great ability in Levitate that gives Lunatone an immunity to Ground-type attacks as well as the ability to dodge Spikes, Toxic Spikes, and Sticky Web. Lunatone's best attempt at a niche in PU as a late-game Rock Polish sweeper that can outspeed threats and some Choice Scarf users such as Rotom-F and Sawsbuck. However, its typing also comes with weaknesses to common types such as Water, Grass, and Dark, leaving it susceptible to priority moves such as Aqua Jet and Sucker Punch and making it harder for Lunatone to set up. It also has a good variety of coverage and support moves at its disposal, although it doesn't have a powerful Rock-type STAB attack and needs a lot of team support to effectively sweep, as Lunatone doesn't hit hard even with Life Orb. It is also outclassed by other Rock-types in the metagame such as Solrock and Golem if it attempts to perform any other role. Its mediocre bulk means that any strong attack will put a dent in Lunatone's chances to sweep.
