Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Dewey Decimal Classification article was read about 400,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 75: each hit it takes is cut by 30 %.
