DESCRIPTION:
Amoonguss is one of the top 5 Pokémon in the tier since it can be easily inserted into any team thanks to its ability to soak up attacks from top tier threats. Amoonguss is one of the biggest threats to hyper offensive rain teams, particularly acting as a
counter to the main special sweeper, Seismitoad. With 252 HP and 36 SpD investment, it is guaranteed that Amoonguss will be 3HKO’ed by Seismitoad’s threatening STAB moves. Hence, Amoonguss can comfortably switch into any of Seismitoad’s attacks and retaliate with a Giga Drain, that is certain to OHKO and restore 40% of HP. However, the opponent will likely switch out into Salamence or another Grass-type counter, where Spore can create immense pressure that may lead to the opponent staying in with Seismitoad. Although it isn’t the most common, rain teams may run Stealth Rocks, which breaks Amoonguss’ ability to safety tank 3 STAB moves from Seismitoad. This can be played around thanks to Regenerator, which commonly allows Amoonguss to sit above 50% and switch in after a KO. Otherwise, Amoonguss can pivot into other ground immunities or water resists until it has recovered enough HP to tank Seismitoad’s attacks and KO it with Giga Drain.
