Mars seems like a really strong house. There are some competing forces within it though.
Brobnar is big and it wants to fight. It is the house with the most powerful creatures and the highest average power.
Logos is a very consistent house. I think there are a lot more B's in this house than Dis and Brobnar but there aren’t any cards that are just amazing by themselves.
Untamed is the most aggressive of all the houses. It is the least afraid to give their opponent aember so long as they are getting more.
Dis is a very disruptive house that has a lot of tools to control the game that are less direct than most.
