Amoonguss

Amoonguss is a great support Pokemon due to its access to Rage Powder, which directs all foes' attacks at itself, and Spore, which puts the target to sleep. Amoonguss is able to shut down some of the best Pokemon in the tier, such as Rotom-W. However, many Pokemon in the tier can destroy Amoonguss, such as Rotom-H, Charizard, and Talonflame. Amoonguss has a weak offensive presence and multiple effects were added in XY that weaken Amoonguss's effectiveness, such as Grass-types' immunity to Spore and the introduction of Safety Goggles, which prevent the holder from being affected by powder moves and weather.
