Seismitoad

Seismitoad's niche over other Ground-type Stealth Rock setters in the metagame lies in its access to Water Absorb, which allows it to threaten common Water-type Pokemon like Slowbro, Tentacruel, and Empoleon more easily. Its above average Speed also allows it to fill a more offensive role on some teams while also providing some defensive utility by offensively checking Pokemon like Scizor, Crawdaunt, Choice Specs Primarina, and Volcanion. Furthermore, Seismitoad fares well against some of the tier's most common threats, such as Mega Aerodactyl and Rotom-H, thanks to its solid defensive typing. Despite not having the greatest offensive stats, Seismitoad can also be somewhat difficult to switch into due to its decent offensive typing and coverage moves such as Hidden Power Fire and Sludge Wave. However, Seismitoad can be easily worn down, as it doesn't have access to reliable recovery, relying on Leftovers to stay healthy. This is aggravated by its vulnerability to status-inducing moves, specifically Toxic, which hinders Seismitoad's ability to check the Pokemon it's supposed to in the long run. Its 4x weakness to Grass-type attacks also holds it back defensively, making it harder for it to check Pokemon like Infernape, Zeraora, and Mega Manectric due to their access to coverage moves like Grass Knot and Hidden Power Grass. Seismitoad also faces heavy competition from other Ground-types as a Stealth Rock setter. Hippowdon's better overall bulk and access to more utility options such as Whirlwind and Slack Off make it the preferred option as a defensive Stealth Rock setter most of the time, as it's capable of keeping a much wider array of threats in check reliably. Seismitoad must also compete with other offensive Stealth Rock setters like Krookodile and Mamoswine, which have far superior offensive capabilities.
