Weezing

Weezing differentiates itself from other defensive Poison-types such as Garbodor and Golbat due to its access to Levitate, which lets it check Ground-types such as Steelix and Rhydon without a weakness to Spikes. Additionally, Weezing's Poison typing allows it to check both Fighting- and Grass-type Pokemon such as Passimian, Decidueye, and Sceptile. Weezing's access to the combination of Will-O-Wisp and Taunt lets it be effective against more defensive teams. Unfortunately, Weezing faces competition for the spot of a bulky Poison-type from Pokemon like Garbodor and Golbat, which have better Special Defense stats, allowing them to better check specially offensive Grass-types such as Whimsicott and Sceptile, as well as having reliable recovery in Golbat's case.
