That was disappointing, I was expecting a twist where the fairy's judging criteria is unusual, like for the handsome guy transform task, they prefer a handsome fairy, not a human, or the fairy's judging people on the 'beauty'/creativity of their magic rather than pure skill. Resulting in D class winning often due to luck (Like failed magic creating unexpected result, that matches what fairy's want) or realizing the true criteria. Though I guess there still a chance the author use it for final few challenges.
