Relicanth

Relicanth is a multifaceted Pokemon in the PU metagame that is able to use its immense physical bulk and useful resistances to Flying-, Normal-, and Fire-type moves from Pokemon such as Dodrio and Rapidash to set up Stealth Rock reliably on both defensive and offensive sets. With access to Rock Polish and a respectable Attack stat, Relicanth can threaten the opposition very easily with dual STAB coverage in Head Smash and Waterfall. Additionally, given its access to both Rain Dance and Stealth Rock and a beneficial ability in Sturdy that allows it to use these two moves reliably, Relicanth has carved out a niche for itself in PU as a dedicated lead on rain-based teams. On the downside, however, Relicanth's overall effectiveness is sometimes limited by its low Special Defense and Speed, as well as its weaknesses to other common attacking types such as Electric, Ground, Fighting, and especially Grass. Despite these flaws, Relicanth is still overall an advantageous choice for defensive and offensive teams alike, given its ability as a Stealth Rock user to pressure PU's most reliable options for hazard removal.
