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.
Drop rate quantification was altered in September 2022 to show the probability that a card rarity would appear in the entire pack. Previously (the rates in brackets), probabilities indicated the chance that a given card would be of a given rarity, and thus the percentages added up to 100%.

Opening packs
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").
Rarities
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.
Some rarities never drop from some pack types. Normally, cards of all rarity except Masterpiece can be obtained by Crafting. Masterpiece cards may only be crafted as a VIP bonus.
