Servine

Servine's main niche is being a bulky Defog user that can take on most Stealth Rock users due to its Grass typing. Access to Contrary and Leaf Storm also allows it to boost its Special Attack while using a strong STAB move, and access to reliable recovery in Synthesis helps Servine stay around longer. A decent Speed tier also lets Servine outspeed base 80 Speed Pokemon like Stoutland and Shiftry. Servine's bulk is decent, but a mediocre defensive typing isn't anything to write home about, and as it relies on Eviolite, it is very susceptible to Knock Off and should be wary of Pokemon that commonly use it. A low Special Attack stat means that Servine won't be doing much damage until it gets a boost, meaning that bulky Pokemon like Assault Vest Hitmonchan and Cryogonal can take it on. Servine also lacks special coverage moves, leaving offensive sets limited to a Grass-type STAB attack and Hidden Power and forcing it to choose which Pokemon it wants to beat. Leaf Storm's low PP also limits how much Servine can break through a team. Furthermore, Servine faces competition as a Defog user from Pokemon like Skuntank and Shiftry, which have either a better typing or better utility. Its main competition is Lurantis, which can hit physically with Superpower, is stronger, bulkier, and can afford to run different items, meaning Servine's only real niche over Lurantis is its Speed.
