The facts on the card
The card carries these facts from its Wikipedia article.
- In solid geometry, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.
- That given point is the center of the sphere, and the distance r is the sphere's radius.
- The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Sphere 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 74 and blocks with 69: each hit it takes is cut by 28 %.
How to get Sphere
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
