I gathered up all the Basic and Expert cards per class found in the Hearthstone collection book. The Basic Cards list contains the mana cost. The Expert Cards list contains the mana cost, how many arcane dust the card disenchants into, and how many arcane dust is required to Craft a specific card.
Hovering the mouse over the cards will display the card’s graphic, info and flavor text added to each card by the developers.
The list can be accessed through the menu on the right-side of the layout under the “Hearthstone: Heroes of Warcraft” sub-menu.
