>ONE good Pokemon means the type isn't shitTangrowth is only decent because it has extremely specialized stats and excels at regeneration, most Grass Pokemon have shit stats with nonexistent coverage. If Tangrowth was pure Water or Fire or any other type, it'd probably be even better.
All the other Grass types in OU are there because they either have a Mega to back them up, or have a secondary typing that offsets all the shitty parts of being Grass well enough to function, Mega Venusaur has both of these. If it didn't have Thicc Fat it'd be trash tier with the other Grass Pokemon.
>>32454249Most Pokemon have something that hits Grass for SE damage without even attempting to specifically counter Grass. It just has that many weaknesses.
