Mega Tyranitar

Mega Tyranitar sets the Sand that powers Excadrill's Sand Rush, and High Horsepower over the more common Dragon Dance gives it valuable coverage into the Steel types like King Gambit and Archaludon that would otherwise trouble the team. Jolly with heavy Speed investment lets it move earlier than most bulky variants. Because Staraptor can also Mega Evolve, the team has the flexibility to bring Tyranitar's Sand Stream or Staraptor's Intimidate depending on whether the opponent has weather control of their own.
