Players will be able to acquire cards through several means.
Common cards will be automatically unlocked for all players after completing the tutorial. These cards all all free-to-play and can be upgraded by spending EOL (Essence of Life). 60 different common cards will exist at launch.
Premium cards, which exist in limited supply, can be acquired through Single Card Boosters, Crystal Boxes (containing 5 cards) and Ancient Boxes (containing 10 cards).
These boxes can be obtained through the in-game shop or by opening level-up orbs as players progress their account level. See more in 'Player Progression'.
