Kinegasus is severely hindered by its level up moveset, which mostly offers physical moves with just average power. If one wishes to use a Kinegasus on their team, it is highly recommended to evolve Psycolt at level 45, where Kinegasus learns its first, and most reliable, special Flying-type move without losing the special Psychic moves that it learns as a Psycolt. It is not a very fast Pokémon either, and despite having a higher HP stat than Yunesis, it is still not bulky enough to take many attacks with its five weaknesses. A moveset with Amnesia and Recover can help make it a special wall and increase its longevity, but it might be more beneficial to have a coverage moveset to deal with any threats.
To guarantee the Natural Cure ability, make sure to catch a Psycolt that has the Early Bird ability. If it has Run Away and it evolves into Kinegasus, it will carry over the Run Away ability.
