>>33249350Unless your Venusaur is underleveled you should have any trouble against Loreli with the broken Razor Leaf, or Giga Drain/Frenzy Plant in Gen3. Also none of her pokemon use any offensive Psychic moves. and none of her pokemon resist Grass so you really shouldn't get any trouble.
>I recently played blue and choose bulbausaur and it wasn't that good for someone who mostly trains his starter.Not sure what were you playing, but my Venusaur smashed the game alone with a super underleveled team
>(zubat, psy, ice, fly etc.)Zubats are annoying, yeah. Pidgey/Spearow don't use any Flying moves until halfway, by that time you have a good counter against them.
Ice don't appear until much late in the game and all of them are half-Water so it's isn't that bad.
Psychic, apart from Sabrina and Koga gyms, only the harmless Abra and Drowzee appear in the wild and they are not very common to worry about.
