Tyranitar

Mega Tyranitar is an incredibly potent and forcing threat that more than rounds itself out with its absurd bulk and support capabilities with Sand Stream and its access to Stealth Rock and the strongest unboosted Pursuit in the tier. With its already great bulk bolstered by sand's 1.5x boost to its Special Defense, Mega Tyranitar can terrorize the likes of Heatran, Zapdos, and Tornadus-T, getting up and keeping Stealth Rock and making them count with forced Pursuit damage. It turns common teammate Excadrill into an immediately fast threat that outspeeds the vast majority of the tier. Rather than playing a bulky all-rounder role, Mega Tyranitar can excel as a Dragon Dance sweeper, with its bulk affording it plentiful setup opportunities to use its powerful STAB Stone Edge and its coverage movepool including Fire Punch and Ice Punch to puncture defensive cores. In some cases, it can even shed its Mega Stone, with Choice Scarf as a surprising tech option to remove key targets and act as a solid revenge killer. However, Mega Tyranitar has a litany of weaknesses to very common types within the tier, with Ground, Water, and Fighting just to start the list off. Its longevity is very poor, so it can't carelessly take attacks, considering it essentially needs to keep somewhat healthy to keep the option to trade damage open. This is exacerbated by its poor Speed, making Mega Tyranitar quite hard to get the most out of without careful and calculated play.
