Bisharp

Bisharp is used mainly for its ability Defiant, which gives Bisharp an Attack boost when it is facing a Pokemon with Intimidate, a common ability due to the amount of physical attackers such as Mega Kangaskhan, Mega Salamence, Landorus-T, and others. Its STAB moves and its impressive base 125 Attack, cover common Pokemon such as Sylveon, Aegislash, and Cresselia. Unfortunately, it suffers from rather poor stats everywhere else; its base 70 Speed can often lead to uncomfortable positions with Sucker Punch mind games when paired with its rather lackluster defenses. However, the free boosts granted by Defiant and its STAB Sucker Punch will always be a force in the metagame as long as Intimidate stays common.
