Okay, so I've been watching a lot of Pokémon YouTube videos recently and since I can't be bothered to make a YouTube channel I'm stick to Wikia, what I'm used to. So, these are my top 10 grass types. I'm going to count the whole evolutionary line and state the final one in that line (for example, I will say Gengar as my favourite Ghost-type even though it's Haunter). I've chosen grass because the first Pokémon in the National Pokédex has that type, so it's the first type you see (ignore poison). So let's get started.
(I'll add reasons later)
