Any player with a POP ID can get their own season scorecard to track league play. Each game played earns you a mark on your card. When a player gets 6 marks, he/she can chose a prize card exclusive to league play. Each season brings new cards to chose from. You can also chose cards from past seasons while those supplies last. Any player who fills up a card earns a booster pack from Heart Gold/Soul Silver. Games played on the last session of a season earn players double marks on their scorecard. Card game marks do not carry over from season to season.
On the first Sunday of each month players also may bring their Nintendo DS and participate in DS Pokemon battles for league credit. Nintendo DS skins are now available as league prizes. DS battle credits will carry over from season to season. Fill up the DS side of the scorecard and win a skin.
