Come to think about it, if Lucy manages to summon the Celestial Spirit King only for August to copy the spells cast in his presence, and supposing that the Celestial Spirit King makes the mistake of using some summoning caster spell that calls other spirits... what would prevent August from circumventing the key requirements and gaining the ability to call spirits to his side?
