Lunatone

Lunatone's only niche is to attempt to sweep using Rock Polish to outspeed most Pokemon in the tier, but unfortunately, Lunatone faces major competition from Omastar as a setup sweeper due to Omastar dealing much more damage than Lunatone. Lunatone's typing hinders it greatly, as it is weak to common typings such as Dark, Water, and Bug and is susceptible to priority such as Sucker Punch from Pokemon like Skuntank. Furthermore, Lunatone is quite slow before a Rock Polish, and common offensive Pokemon in the tier such as Primeape, Kabutops, and Floatzel are able to outspeed it and take it out with ease, and poor physical bulk and a bad defensive typing limit its ability to actually set up. Lunatone finds itself lacking the power to hit bulkier opposing Pokemon such as Eelektross and Jellicent, and these Pokemon are able to whittle it down with their STAB moves.
