Pinsir

Mega Pinsir has high Attack and Speed stats along with Swords Dance, which make it an excellent late-game sweeper. It also has good bulk, meaning that it has many opportunities to set up Swords Dance. Once Pinsir Mega Evolves, it gains a Flying typing along with the ability Aerilate, changing its Normal-type attacks into Flying-type attacks, allowing Mega Pinsir to easily revenge kill many threats with Quick Attack. Mega Pinsir is also fast, being able to outspeed threats such as Kyurem-B and Landorus. However, Mega Pinsir has a devastating weakness to Stealth Rock, meaning Rapid Spin support from Armaldo or Forretress is necessary. Its Flying typing adds a weakness to Electric- and Ice-type attacks while also stacking a weakness to Rock-type attacks. Mega Pinsir also faces competition from Mega Scizor and Mega Heracross, as Mega Scizor is a bulky setup sweeper with reliable recovery, while Mega Heracross is a fearsome wallbreaker.
