What one wizard do you not have?

What type of wizard do you not have? If you have two accounts please state so and which you don't have on each, and why you don't have that type, weither it be because you picked the others first or you don't like that school and why. As well what is your favorite school, and why. Don't just say "Because ___ is the best!!!" that doesn't work. Just comment or email me thanks
