Suicune

Suicune is a great setup sweeper thanks to its solid defensive typing and natural bulk, which also allows it to check prominent threats such as Scizor and Mega Aerodactyl. Furthermore, with access to both Rest and Calm Mind, Suicune can also function as a fairly sustainable bulky sweeper. Because of its ability, Pressure, and its potential to set up fairly easily, Suicune is able to threaten defensive teams a lot. Pressure also allows it to break through certain Pokemon that would normally check it, such as Volcanion. Suicune also has a very decent base Speed stat for a bulky Pokemon, allowing it to hit or set up against Pokemon like Mamoswine and Togekiss. However, since it doesn't have access to reliable recovery, Suicune is forced to rely on Leftovers or Rest in order to stay healthy. It's also held back by its weakness to Electric and Grass, which are common typings, making it easily exploitable by Pokemon like Mega Manectric and Celebi.
