When you throw a Pokeball and Gardevoir appears, she appears to have a force-field around her. However, it doesn't seem to do anything. Does Gardevoir have any use?
The field surrounding Gardevoir is a giant reflection bubble, reflecting and doubling the damage of any projectile that opponents try to toss inside or use while inside. It doesn't attack opponents directly, but you can feel free to camp nearby and shoot your own projectiles outwards while being safe from most anything that doesn't come up and punch you in the face.
