Salamence

Mega Salamence is one of the best Mega Evolutions of the format and should therefore be a top consideration when picking your team. Access to Intimidate before Mega Evolving helps provide excellent support, especially for partners like Amoonguss and Sylveon. Further, its great defensive stats and resistances to common types such as Fire, Water, and Grass make it easy for Salamence to switch in and out to activate it. Sets utilizing Draco Meteor tend to take advantage of this even more, as the Special Attack drops encourage switches. Aerilate and access to moves such as Double-Edge and Hyper Voice allow Mega Salamence to deal massive damage. Flying also has very good neutral coverage, so Mega Salamence can easily get away with running mono-Flying-type attacks. High Attack and Special Attack, and the movepool to support both, allow it to function with a variety of sets. The ability to go mixed is a big advantage Mega Salamence has over other Mega Evolutions. This can also make Mega Salamence difficult to deal with, as the opponent must guess the set in order to handle it appropriately. A high base Speed allows it to outpace the majority of the metagame, even ordinarily very fast foes such as Gengar and Terrakion. It is, however, vulnerable to all forms of speed control. A 4x weakness to Ice often leaves it threatened, as, despite Ice-types being uncommon, it's a common typing for coverage. When Intimidate support is unneeded, Mega Salamence can often face too much competition as a Mega Evolution to be optimal. For example, Mega Kangaskhan has a stronger Double-Edge, and Mega Gardevoir has a more powerful Hyper Voice.
