Pokémon GO: Grass-type Pokémon in the Arena

During the current Pokémon GO event, you will encounter many Grass-type Pokémon. These are not useless, but effective helpers in the arena.

The Grass-type event runs until the evening of May 8th, providing you with many Grass-type Pokémon during this time. This Pokémon type is well-suited for attacking gyms. Because against particularly popular defenders, Pokémon like Oddish have good chances in battle. Some of the frequently found Pokémon fulfill their role as prestige (explained further below) particularly well. On Reddit, user Zyxwgh recently showed why Grass-type Pokémon are not useless.

Keep in mind that some movesets that can arise from bad luck might thwart your plans. This could significantly limit effectiveness against the mentioned Pokémon.

Grass-type Pokémon as Arena Attackers

In the battle for gyms, some defenders are found more frequently than others. Popular ones include Vaporeon and Rhydon. Therefore, you will read about them often in this article. They have weaknesses against Grass-type Pokémon, which you can now often find in the wild.

Oddish: Oddish is considered one of the best attackers against Vaporeon, as the Water-type Pokémon reveals its weaknesses against the Grass type.
Bulbasaur: Bulbasaur can help you evolve into a strong Venusaur, which is strong against Vaporeon.
Tangela: As an attacker against the mentioned Vaporeon and Rhydon, Tangela is quite suitable.
Gloom: As an attacker against Vaporeon, Vileplume does okay. However, it shows its strength as a prestige.

Grass-type Pokémon as Gym Prestige

When you increase the prestige value of a gym, it levels up and opens more slots for defenders. Many of the Pokémon you can catch during the event weekend are suitable as prestige. To find the best prestige against certain defenders, Reddit user Zyxwgh has provided a tool that helps you in your search. Here is the prestige tool on pokebattler.com

Bulbasaur: Catch many Bulbasaur to evolve them into Ivysaur or Venusaur. Both are excellent as gym prestige against Vaporeon and Rhydon.
Paras: With the right attacks, a Parasect is one of the best prestige against Vaporeon. The preferred attacks are Fury Cutter and Solar Beam. It also works as prestige against Earthquake Snorlax or Earthquake Rhydon. Combined with other Pokémon, it works as prestige against Snorlax.
Tangela: With Vine Whip and Leaf Tornado, Tangela has one of the best Grass movesets available. It is excellent as prestige against Vaporeon, Rhydon, and Snorlax and is good against Snorlax. However, it requires a Revive and a Super Potion.
Hoppip: The evolution Skiploom is the best prestige against a Rhydon with Mud Shot and Earthquake because it is resistant to Ground attacks. It performs well against Vaporeon and Rhydon, but one should avoid opponents with Stone Edge.
Gloom: Vileplume is a great prestige against Vaporeon and Rhydon without Ground attacks. In the 1000 CP to 1100 CP range, Gengar is also a good prestige.
Oddish: Bellossom is, like Vileplume, a good prestige against Vaporeon and Rhydon without Ground attacks. Victreebel is a good prestige against Vaporeon and Rhydon with Ground attacks – Use Razor Leaf and Leaf Blade.
Sunkern: Sunflora with Seed Bomb and Solar Beam is a fast prestige against Vaporeon and Rhydon without Megahorn.
Chikorita: Meganium is, like Sunflora, a good prestige against Vaporeon and Rhydon without Megahorn.
