Beta Reward

Beta was the first set to feature a “Reward” series of cards, which were available to earn by completing Daily Quests. At the time, cards were the only Rewards given out, prior to the Reward Chests being added to the game. Beta Reward cards consisted of 48 individual units and 1 summoner (as with all cards, each of these has a Gold Foil variant).

They can be filtered for on the Items and Market pages with the option seen below:
