Morelull

With very good defensive stats, a passable Special Attack stat, and a cool signature move in Strength Sap, Morelull can make for a relatively good defensive pivot. Spore and Moonblast add to this by putting switch-ins to sleep and catching incoming Fighting-types, respectively, as does its ability, Effect Spore. However, Morelull is commonly outclassed by the many other bulky Grass-types such as Ferroseed, Lileep, and most of all, Foongus, which also acts as a defensive pivot with Spore but has access to Regenerator. With the rise of Poison-types in SM, Morelull struggles to find a teamslot over Foongus due to its 4x weakness to the type, but its Fairy typing and slightly wider support movepool can certainly grant it a niche. It also struggles with a relatively passive playstyle in a very offensive metagame, making it unwelcome on many teams.
