Card packs are the primary means of obtaining cards. Card packs may be purchased using in-game currency Resources, or gained as rewards in Events. A free pack may also be claimed at regular intervals.
Missing cards may be obtained by Crafting. Cards may not be traded between players.
Once acquired, a card pack may be opened at any time. Opening a card pack provides a fixed number of random cards, generally from the same card set. These opened cards may be new for the player, or already owned ("duplicates").
- New cards are added to the player's collection, and may subsequently be added to Decks.
- Duplicate cards are converted to runes () and mana orb () Resources.
Each card has a rarity of either Common (), Uncommon (), Rare (), Mythic (), or Masterpiece (). Progressively rarer cards are less likely to drop from packs, according to drop rates set by the publisher. Drop rates may change at any time.
