If you want a bulky Grass type,then Ferrothorn's your Pokemon with this moveset
Flash Cannon/Metal Claw
If you want a fast one then I recommend using Simisage with this moveset
~ Nasty Plot
~ Giga Drain
~ Focus Blast
~ Hidden Power Ice / Hidden Power Rock
And here's a Pokemon that might go nicely with other Pokemon in your team
And thatsall I can think of.Hope I helped!
These are only for ingame.If you want competitive,please comment.
