Zoroark would be my vote.

Too common.

Weh.

Guess I'll add on to what Zel said and suggest Shaymin.

I think you'd make a pretty adorable celebi or shaynin

Best one? Definitely that Eldegoss.
One I wanna see? That’s a harder question. Keeping to your niche of dummy thick Grass-Types/plants, Comfey comes to mind. Not a grass type proper (which is dumb because she’s holding all those flowers), but would still be interesting to see.
I honestly would’ve voted on myself (the Leavanny), but that just seemed imprudent and selfish.

I'd go for Bellosom or Spinda <3

My favorites so far are Bellossom, Dewgong, and Purugly

I know you said Zoroark is too common, but how about Zorua or Hisuian Zorua?

Spinda!
