Venusaur

Deprived of consistent sun following the Chlorophyll + Drought ban, Venusaur is trapped in a tier it no longer belongs in. It can still be used on non-Drought teams as a way to "countersweep" opposing sun teams, but considering sun teams are almost always stall oriented, Venusaur is not exactly a great answer to them. Being forced to manually set its own sun if not facing a Drought team and then having to find turns to set up Growth to be threatening means the effort-to-reward ratio is way too imbalanced to merit using Venusaur in most situations. Outside of sun, Venusaur is outclassed by Ferrothorn, Amoonguss, and Celebi in pretty much all aspects despite sporting nice balanced stats and the ability to check Keldeo.
