Gallade

Mega Gallade is a decent wallbreaker thanks to its high Attack stat paired with its strong STAB moves and useful coverage moves in Knock Off and Ice Punch. Having access to Swords Dance allows Mega Gallade to boost its Attack stat to even higher levels, which can make it difficult for defensive teams to take on. Knock Off is particularly useful for pressuring bulky Psychic-types that other Fighting-types such as Mega Medicham tend to struggle with. Mega Gallade's good Speed tier allows it to outspeed foes such as Kartana, Garchomp, Mega Medicham, and Tapu Lele, giving it an edge against some offensive teams. Its decent bulk, notably in Special Defense, gives it setup opportunities against a majority of defensive Pokemon. It also allows Mega Gallade to take a hit from certain offensive threats in a pinch. Unfortunately, it faces competition from other Fighting-types like Mega Medicham, which doesn't rely on setup in order to beat bulkier teams, and Mega Heracross, which has an easier time against stall teams as well as a more useful defensive typing. Despite the fact that its bulk isn't terrible, Mega Gallade's poor defensive typing means it's still prone to being revenge killed by a bunch of common faster Pokemon such as Tornadus-T as well as most Choice Scarf users; this is especially true after a Defense drop from Close Combat.
