Amoonguss

Amoonguss is a potent defensive wall due to its good defensive typing, which enables it to check dangerous foes such as Azumarill, Primarina, and Zarude, combined with its access to Regenerator. Access to Spore allows Amoonguss to shut down an opposing foe completely, making it harder to play around and offensively check due to pressuring opponents to choose sleep fodder. Its Poison typing additionally gives it an edge over other common Grass-types, as it is able to threaten Tangrowth and Zarude with Sludge Bomb, which also prevents them from switching in to absorb Spore. However, despite Amoonguss's good defensive typing, it struggles against metagame staples like Salamence and Crobat. It can also be overwhelmed by Pokemon it is supposed to check due to their access to coverage, such as Ice Punch from Azumarill, Psychic from Primarina, and Air Slash from Keldeo. After using Spore, Amoonguss is easy to take advantage of by Pokemon that take little from its other moves such as Galarian Slowbro, Celesteela, Skarmory, and Cobalion. Amoonguss faces competition from Tangrowth as a defensive Grass-type wall, which can opt to run Assault Vest sets to check specially offensive foes such as Thundurus-T better, not be neutral to Excadrill and Zygarde-10%'s Ground-type STAB, and avoid being setup bait for Swords Dance Cobalion if something else has been hit with Spore.
