The facts on the card
The card carries these facts from its Wikipedia article.
- They play a role in maintaining the charge balance of the atmosphere.
- The main components of air are molecular nitrogen and oxygen.
- Due to the strong electronegativity of oxygen and oxygen-containing molecules, they can easily capture electrons to form negatively charged air ions, most of which are superoxide radicals ·O2−, so NAI are mainly composed of negative oxygen ions, also called air negative oxygen ions.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Negative air ions article was read about 8,600 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 58: each hit it takes is cut by 23 %.
