Tyranitar

Despite numerous weaknesses to many top-tier threats, Tyranitar still stands out as one of the most versatile bulky offense Pokemon in the metagame. Being one of the only two sand setters in the format, Tyranitar faces a lot of competition from Hippowdon, which has superior bulk and typing that allow it to wall any physical attacker with ease. However, due to its Rock typing, Tyranitar gets a 50% Special Defense boost under sand, which can be helpful when playing supportive roles. Taking on a more offensive approach when using Tyranitar is where it really shines, though. Depending on its item, Tyranitar can play a variety of roles, including that of a sweeper, bulky Pursuit trapper, or just support. Its Mega Evolution not only increases its overall bulk but also boosts its Speed, which puts it in an important Speed tier after one boost. Thanks to sand also breaking potential Focus Sashes, Mega Tyranitar differentiates itself from other Dragon Dance sweepers such as Mega Salamence, Mega Charizard X, and Mega Gyarados. With its huge movepool and excellent stat distribution, Tyranitar can run both physical and special sets or even go mixed, with moves such as Fire Blast and Ice Beam letting it easily check some of the threats that would otherwise be troublesome such as Ferrothorn and Landorus-T. Tyranitar is a staple on stall teams due to its ability to get rid of Mega Gengar, a huge threat for stall teams because of Shadow Tag. It is also a must on sand teams, being one of the only two setters that can help Excadrill activate Sand Rush just by switching in. While Tyranitar's typing theoretically lets it handle Fire-, Flying-, and Ghost-types, some of these usually carry Fighting-type moves as coverage, and they can outspeed and OHKO Tyranitar. Tyranitar is also at the mercy of some of the most prominent Fighting-types seen in Battle Spot, such as Blaziken and Breloom. Tyranitar's Speed is also a letdown, as even when it has a Choice Scarf equipped, it fails to hit an important tier, further limiting its effectiveness against the threats that it's supposed to match up well against, such as Mega Gengar, Weavile, and Alakazam.
