Cards
Cards are the tools of the Hearthstone Heroes. Each player constructs a thirty Card deck made up of three main types of cards: Minions, Spells, and Weapons.
Basic Cards are the "starter" cards that form the foundation of each heroes class, and are earned each time you play a game (you can have up to two of every basic card in the game in your collection).
Expert Cards are cards that can only be found in Expert Card Packs, or created using the Crafting system (certain achievements grant them as well). They’re distinguished by their rarity jewel in the center of the card.
You can have any number of expert cards in your collection, though only two of any common, rare, or epic card, and one of any legendary card, can be placed in a deck.
Card Properties
In the top left corner of a card, a number on a blue crystal defines the cards mana cost, the box below the artwork specifies the effects of a card and, for minion cards, the numbers at the bottom left and right corners of the card indicate that minion's Attack Damage and Health, respectively. Weapon cards will have a durability number instead of health.
The center of a card represents the Rarity of a card. A basic card will have nothing in the middle, whereas a common card will have a white jewel in the center. Rares, Epics and Legendary Cards have blue, purple and orange jewels, respectively.
On top of this rarity, there are also Golden Cards. Golden Cards do not have any benefit in their stats, but they are gold rimmed and the artwork is animated, they are much more aesthetically pleasing. Gold cards can be disenchanted for more Dust than their non-golden counterparts.
