The facts on the card
The card carries these facts from its Wikipedia article.
- It is a white, caustic, alkaline, crystalline solid at room temperature.
- The broadly used term lime connotes calcium-containing inorganic compounds, in which carbonates, oxides, and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
- By contrast, quicklime specifically applies to the single compound calcium oxide.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Calcium oxide article was read about 180,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 48: each hit it takes is cut by 19 %.
