Tyranitar

With good Attack, Special Attack, and bulk, Tyranitar has a lot going for it. What's more, its ability Sand Stream induces sand upon switching in, which boosts Tyranitar's Special Defense. Sand is seen as a neutral weather, as it neither boosts nor weakens any types offensively; there is also a lack of Pokemon able to take advantage of sand in VGC. Because of this, Tyranitar is often used to take on opposing weather setters, mainly Mega Charizard Y. Tyranitar has an extensive movepool, which, along with its stats, allows it to play multiple roles, including that of a special attacker and a Dragon Dance sweeper. While Tyranitar's Speed may seem lacking when compared to its other stats, it is enough for Tyranitar to effectively use a Choice Scarf. Tyranitar is also blessed with an incredibly powerful Mega Evolution. With a base 164 Attack stat, Mega Tyranitar hits incredibly hard, and with massive 100 / 150 / 120 bulk, it can be very difficult to take down.

It is important to know that most Dragon Dance-lacking Tyranitar should be special attackers due to the many Intimidate and Will-O-Wisp users in the metagame. Tyranitar's Rock / Dark typing leaves it with seven weaknesses, four of which are common. While Tyranitar's movepool gives it a lot of options, to effectively use them, Tyranitar must compromise STAB moves for coverage moves or vice versa, leaving it unable to win certain match-ups it otherwise could. Without a Choice Scarf, Tyranitar is relatively slow, leaving it vulnerable to opposing attackers. Most importantly, Tyranitar is complete setup fodder for Power-Up Punch Mega Kangaskhan.
