Seismitoad

Seismitoad is a rather unique Water-type Pokemon in that it can be played in a variety of different ways. Seismitoad can go on the offensive as a rain sweeper or go on a more defensive route with its good typing and set up Stealth Rock for its team. It is also a good check to several Water-types in the tier by utilizing Water Absorb and Substitute. Seismitoad's typing comes with several benefits: Seismitoad can't be paralyzed by Thunder Wave, so its rain sweep will not be ruined, and while on the defensive, it gives Seismitoad good resistances to some of the most common offensive types, such as Rock and Fire. However, a mediocre movepool and average stats bring Seismitoad down a bit. It doesn't hit super hard with its moves unless they're boosted by Life Orb and rain, while its coverage is limited to Sludge Wave and Grass Knot to hit Water- and Grass-types that resist Seismitoad's Water-type STAB. A lack of reliable recovery also makes it hard for Seismitoad to take repeated hits, while other bulky Water-types such as Alomomola and Slowking give it huge competition due to that reason. All in all, Seismitoad's unique assets in the roles it plays is definitely something to take into consideration.
