So the reprint of packs in the 3x card formats have inspired me to bite the bullet and finally start investing int his amazing game. But what is clear for me, as I teach friends using the 2x core set I have, is that I am not really present to the non-obvious strategies of the game, and particularly of the individual houses. I was wondering if anyone could direct me to any resources of that sort? Thanks so much!

Thats some basic info which includes house specific information. Some of it is CCG related, but still relevant.
