Collectible cards are cards which are available for players to collect and use in their decks. The majority of all playable cards are collectible cards. Players can view their collectible card collection through the collection manager.
Collectible cards are to be distinguished from uncollectible cards. Uncollectible cards cannot be collected or added to normal player decks. They are only brought into play through collectible cards, through certain Hero Powers, or in specific game modes such as Tavern Brawl or Adventures.
