Suicune

Having been considered one of the best sweepers in existence two generations in a row is no small feat, and although Suicune has now fallen into UU, it can still hold its own in this environment. Its pure Water typing is amazing, as it gives it few weaknesses and a very wide range of neutral coverage with its STAB moves. Its stats are just right for it to do virtually anything it wants, from sweeping to being one of the sturdiest walls in the game. Since it possesses such an array of support moves, such as Calm Mind and Roar, it's also a great team player. However, it's not all peaches for Suicune, as many of its greatest enemies happen to be some of the most used Pokemon in the tier, including Roserade, Raikou, and Zapdos, which makes it difficult for Suicune to truly shine. Fret not, as despite these hinderances, Suicune is sure to leave its mark in any battle it takes part in.
