Then the person they're going to reincarnate is going to consume a large number of pieces. For example, Kuroka's master had to use 2 bishop pieces on her. But then again, Sirzechs had to use 2 bishop pieces on Macgregor Mathers. Kuroka was stronger than her master and killed him. So yeah a king can reincarnate someone as a devil far stronger than them. Although it'll consume a whole lot of pieces. But you could even be a Satan-class devil and take a whole lot of pieces reincarnating someone at the level of Ultimate-class devil.
