Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Anhydrite article was read about 24,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 38: each hit it takes is cut by 15 %.
