I personally disagree with tangrowth for anything more than C based on its standard set. Its typing is particullary bad for a physical wall since its neutral to dragon, fighting, rock and weak to bug. It also lacks anyway to support the team bar the unreliable sleep powder. I simply dont see any reason to use it over other physical walls with superior typings and movepool like skarmory or hippowdon. However the offensive clorophyl set is something i would personally like to be more looked at as it can use its combination of bulk and power to become a powerful mixed tank. Any thoughts?
