Amoonguss

Amoonguss is one of the best support Pokemon in the metagame, capable of redirecting attacks with Rage Powder or putting foes to sleep with Spore. It is bulky enough to live most attacks, and the added survivability from Regenerator allows it to perform its role repeatedly throughout a match. Additionally, Pollen Puff ensures Amoonguss's teammates can also remain healthy. Setup Pokemon, such as Dragon Dance Zygarde or Kyurem-B and Calm Mind Tapu Fini, benefit the most from Amoonguss's support and can make up for its minimal damage output. Due to its low Speed and Spore, Amoonguss also works well both with and against Trick Room teams, as it can then send most Pokemon to sleep before they move. Trick Room users such as Porygon2 and Diancie also appreciate the redirection support while setting it. Despite being able to stomach most hits, Amoonguss must be wary of Fire-types such as Heatran and Incineroar as well as Psychic-types such as Tapu Lele and Necrozma, requiring teammates to deal with them such as Urshifu-R and Heatran, respectively. The presence of Misty Terrain hampers Amoonguss's Spore, so terrain setters such as Tapu Lele and Indeedee-F, or Metagross with Steel Roller, are essential to remove it. Opposing Grass-types such as Rillaboom, or Pokemon holding Safety Goggles, can also be troublesome, as immunity to powder moves lets them mostly ignore Amoonguss and attack its partner. Blastoise, its biggest competitor as a redirector, doesn't share this drawback.
