Ghost and Psychic
dark types or ghost types
Psychic. Although all types of attacks excep normal attacks affect a ghost pokemon but psychic is most effective.
You can beat it easily with Dark, Bug, and Ghost type Pokemon. It is least effective by Psychic, and Fighting.
I would choose a Dark or Ghost type
Can kids have psychic powers?
Psychic is super effective and normal has no effect against eachother with ghost
You can comment on anything when you have psychic powers. There is no requirement to have psychic powers to make a comment on any matter.
There is no verifiable evidence of psychic powers of any kind.
No, there is no Pokemon that is psychic and ghost. (To, be honest, i thought there was... :( I hate being wrong.)
Ghost or dark type moves are super effective against Physic.
