Is there anything special to them, or is their only perk being only usable by wizards of their individual school? I always thought that it emphasized bringing up cards of the school corresponding to them: like most life cards will be brought up each turn if it's a novice life deck. I'm contemplating whether I should get it for 560 gold, or the Pharaoh's Deck for 420 from the bazaar. It's only a difference of 130 gold, so it isn't too much of a gamble.
