A lényegesebb dolgok:

Néhány class challenge hogy pontosan mit is kell csinálni a kártyákért:

Mage
If you've beaten Heigan the Unclean you can do the Mage challenge against him with a secrets-heavy deck (including the new Duplicate card).
Hunter
The deck is made up of all Webspinners.
Druid
The deck uses 1/4 gargoyles that heal to full at the beginning of your turn, and buff cards to synergize with that. Completing a Class Challenge unlocks that class's card.
