Well, this won't surprise many people, but Water is my favourite type. I have made it my mission to create unstoppable water teams in all the games I have played, I am a Pisces also and just love water in real life in every sense. Water relaxes me, the sound of rain beating down calms my nerves and helps me sleep and ever since I was a child, I have had vivid dreams about being able to breathe under water and swimming with marine life.
I have been thinking, and I really don't have a second favourite, most of them are, I just know that I'm not particularly a fan of Grass, Poison, Ground and Steel types.
