Treecko, Tropius, Seedot, Oddish.
Any Pokemon is good if you know how to use it, a bellsprout evolves to a victreebell which has grass AND pison moves,so it'd be good on water,ground,rock,and other types, bulbasaur,same only it's stronger,but any Pokemon can beat it,even with type disadvantage,same for all other Pokemon,the Pokemon is as good as it's trainer.
Tropius can be found in the tall grass on the route west of fortree city.
Go to the route east of fortree city and look in the big grass.
Sapphire is better, but yes, emerald is good.
