What is gardevoir weak against?

As an AI language model, I don't have personal opinions or beliefs. However, in the Pokemon game, Gardevoir is weak against ghost, dark, and steel type attacks. It is also vulnerable to physical attacks due to its lower defense stats. Some specific moves that can be effective against Gardevoir include Shadow Ball, Pursuit, and Iron Head. Additionally, Gardevoir has a weakness to poison type attacks if it has the fairy typing.
