TLDR; Dominate Grass/Poison with Charizard. Otherwise, use the following:
- Any Fire type
- Pidgeot with:
- Wing Attack
Most of your garden-variety Grass type Pokemon have a Poison dual-type. This complicates things when you’re picking a counter.
There are 4 Types that are super-effective against Grass/Poison:
But it turns out that Fire is the only safe option, for two reasons:
- Most Flying type Pokemon do not have Flying move-sets
- Ice (and Psychic) type Pokemon tend to have a Water dual type that makes it vulnerable to Grass
This is your best option against Grass/Poison.
- Fire is both strong and resistant vs Grass.
- Fire types tend to have Fire moves, so you benefit from STAB
- With Fire, you don’t have to worry about a dual-type screwing things up
Fire occasionally dual-types with Flying. Flying happens to be strong and resistant vs Grass too. Turns out the Fire/Flying dual-type has double resistance to Grass attacks.
In other words, Charizard is pretty much untouchable vs Venusaur, Victreebel, and Vileplume.
There are no pure Flying Pokemon. But there are plenty of Flying dual-types.
The problem with Flying is that most of the good Flying types don’t have any Flying attacks.
Of the Flying types that have dual Fighting attacks, only Pidgeot’s is ideal.
- Pidgeot (ideal)
So the next time you’re grinding Pidgeys, hang onto a couple with good IVs and try to evolve one with Wing Attack / Hurricane.
This Trainer Tips episode is what got me thinking about practical uses for Pidgeot:
If you have a Charizard, you can totally dominate Grass/Poison.
In the meantime, don’t grind and cannon-fodder all your Pidgeottos. Save some with good IVs and try to evolve a Pidgeot with the ideal Flying move-set.
