All in the Family: Each class belongs to one of the city's three factions. Your class cards and neutral minions all fall into that faction's theme. The affiliations are:
Grimy Goons: Hunter, Paladin, WarriorKabal: Mage, Priest, Warlock
Jade Lotus: Druid, Rogue, Shaman
Faction Specials: Aside from class affiliations, the three factions each have their own unique twist.
Multi-Class Cards: Some neutral minions are only available to members of their faction; for example, a Grimestreet Informant (a member of the Grimy Goons) can only be in Hunter, Paladin, or Warrior decks.
