Offensively, the Psychic-type can act as a sweeper due to typically high SPD and SPEC. ATK. Furthermore, it can often learn moves of other types to deal with a wide range of Pokemon. However, the greatest disadvantage is that Psychic attacks are unable to affect Dark-types, their main predator, but it can be eliminated by using Miracle Eye, leaving Steel as the only type capable of resisting Psychics&allowing it to otherwise sweep freely. Its defensive capabilities are generally poor, with low health. Possibly compensating, it has access to techniques like Recover. Still, it can often only survive special-based hits, but can easily be defeated by one or two high-powered physical attacks.
