- It forms as an evaporite mineral and as a hydration product of anhydrite.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gypsum article was read about 280,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 82: each hit it takes is cut by 33 %.
