Card: Professor McGonagall tallying Gryffindor and Slytherin's house points.
Reasoning: 'Strict but fair' is the best phrase to fit Professor McGonagall. The Justice card is about balance and fairness, not punishment or reward. About doing what is correct and necessary, even though it may sting a bit (such as taking points from Gryffindor...), because in the long run it is the wisest thing to do.
