Weezing

By virtue of its Poison typing and high Defense stat, Weezing can check some of the most threatening Grass- and Fighting-type Pokemon in the tier, like Virizion, Venusaur, Hitmonlee, and Gurdurr. Weezing also has a very colorful movepool, with moves like Will-O-Wisp, Taunt, Toxic Spikes, and Flamethrower letting it provide great utility to its team. Unfortunately, Weezing is quite easy to wear down due to its only form of recovery being the unreliable Pain Split. While it does have a great Defense stat, its Special Defense stat is quite poor even when invested, meaning that it struggles to take on strong special attackers; mediocre offensive stats coupled with a reliance on Will-O-Wisp to do damage worsen this problem, as special attackers can usually switch into Weezing with impunity. Weezing also faces competition from Garbodor due to the latter's higher Special Defense and access to Spikes, though it maintains its niche with not only its unique movepool but also its ability in Levitate, which lets it take on Ground-type Pokemon like Rhyperior and Steelix better.
