Countering Sierra’s Shadow Pokémon

Nidoran (F)

Nidoran (F)

Sierra’s Shadow Nidoran (F) comes with a couple of weaknesses that include Ground and Psychic type attacks. Nidoran will go down pretty quickly, so you will likely want to pick a Pokemon that can withstand its attacks so you can save your energy for her 2nd Pokemon. Nidoran can know bite, which can destroy any lead psychic type Pokémon you throw out. Therefore it may be wise to not lead with a Psychic type.
