Mario Super Sluggers cards
To coincide with the North American release of Mario Super Sluggers in August 2008, an online card game was created on www.mariosupersluggerscards.com. The cards to collect for it were found on kid-friendly sites like 4KidsTV and Nick.com and even YouTube (mainly to promote the Mario Super Sluggers game itself). There was also a section that allowed users to chat with each other on the Tips & Talk section (using a forum's layout).
Materials on the main site itself included: cards of each character (not including characters' alternate colors), each captain's Star Swing and Star Pitch, each team, and the five default stadiums. Users could do many things with their cards, such as swapping them with other users, and it was also discovered that it was possible to clone cards by swapping with themselves and accepting the swap. Although the main procedure was to obtain the starting cards via banners at kid-friendly sites, people noticed that each card link had a five letter code and decided to save them for future reference. As users obtained more character profile cards, they were also able to choose icons of available Mario Super Sluggers characters. While on the site, Lakitu gave the users hints from time to time about their collections.
If a user completed their Mario Super Sluggers card collection, they were able to receive a poster download featuring Mario and all the cards that they had collected. The Mario Super Sluggers card game has ended, and the site is no longer up.
Below is a list of the cards, categorized by their respective levels.
Level 1 cards (character profiles)
Level 2 cards (Star Pitches/Star Swings)
Level 2 featured the Star Swing/Star Pitch of every Team Captain. They were made by making double plays with Level 1 cards.
Level 3 cards (team cards)
Level 3 included cards of each team in the game. They were made by making double plays with Level 2 cards.
Level 4 cards (stadiums)
Level 4 featured the five stadiums that do not need to be unlocked. They were made by making double plays with Level 3 cards. Luigi's Mansion, Daisy Cruiser, Bowser Castle and Bowser Jr's Playroom are the only Stadiums that don't appear as cards in the collection.
