Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Current source article was read about 26,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 44: each hit it takes is cut by 18 %.
