As the player battles their way through matches, they collect more power cards. If the player has trouble passing a round, they can choose to go into the Free Play area, where they can face off with different characters and unlock more cards before returning to the level. The game features a Deck Builder option that allows the player to customize their deck and input any new cards. One can use up to three different decks in a battle, depending on what type of battle it is.
The game also features daily quests. When you complete one, you get a special card. New cards with new quests were added daily until 2016.
