Nexon's TCG MMORPG Astellia Online will enter closed beta testing for a pair of weekends towards the end of June. Recruitment for CBT will kick off today and run through June 15th. To celebrate the imminent start of closed beta, Nexon sent out a new trailer.
Astellia will feature five playable characters (Warrior, Archer, Rogue, Scholar and Mage) and the ability for players to collect cards to build decks. During battle, cards are used to assist players by attacking enemies or buffing the player.
You can check out the Astellia Online site, though it is in .Korean only at the moment.
