I’m a newb to this game. Do the different houses have general themes like other games? Such as in MTG, red is aggro, blue—>control, etc.

Yes, each house favours certain tactics linked to the fiction.

There are two news articles re. The intro decks (4 houses described in each) plus the very first news articles for each faction that give a good overview.
