Suicune

Water

Sporting great defensive stats, amazing defensive typing, and decent natural Speed, Suicune is able to wall and stall many Pokemon in Monotype such as Slowking and Tapu Lele. Thanks to its ability in Pressure, Calm Mind, and its natural bulk, Suicune can stall out menacing walls such as Celesteela, Ferrothorn, and Toxapex one-on-one. It is also able to effectively stall out menacing attacks like Tapu Bulu's Horn Leech with Pressure. Due to its lack of reliable recovery, Suicune is extremely vulnerable to entry hazards, status, and other chip damage leaving it unable to reliably switch into attacks. In addition, having Scald as its only offensive move makes it vulnerable to Water-immune Pokemon such as Gastrodon and Mantine. Furthermore, Suicune's heavy reliance on Leftovers makes it extremely vulnerable to Knock Off.
