The goal here is to try and grasp the overall strength of the six houses. In order to do so, I look at the average rating for each Standard-legal, house-specific card (including dual house cards). I discount any rating less than 3 (every house has clunkers which don't make it into any deck). I take ratings of 3 or greater, subtract 2, and then sum them together to find the total rating for each house.

Alternative suggestions for rating the houses are welcome.
