Um... Really? Is that a typo?....maximum number of Statutes the Azorius Logistician may have constructed is equal to his Wisdom modifier - 10.
Awesome concept here, by the way, and the classes look really good on the whole. Only other thigns that springs to mind is that the Logistican doesn't really have anything to do with logistics - perhaps Azorius Arbiter or Azorius Lawmaker would be a better fit?
Also, you're doing them in the wrong order. The correct order is:
Simic -> Izzet -> Dimir -> Golgari -> Boros -> Selsenya -> Azorius -> Orzhov -> Rakdos -> Gruul. This is the scientifically established correct priority order for the guilds, and has nothing whatsoever to do with my personal preferences - in fact, you doing it the categorically wrong way is nothing less than a mortal sin and an insult to every thinking, logical person in the world.
