Hyperbolic geometry, an Uncommon card

The card carries these facts from its Wikipedia article.

• The parallel postulate of Euclidean geometry is replaced with: For any given line R and point P not on R, in the plane containing both line R and point P there are at least two distinct lines through P that do not intersect R. The hyperbolic plane is a plane where every point is a saddle point.
• Hyperbolic plane geometry is also the geometry of pseudospherical surfaces, surfaces with a constant negative Gaussian curvature.
• Saddle surfaces have negative Gaussian curvature in at least some regions, where they locally resemble the hyperbolic plane.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hyperbolic geometry article was read about 110,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 78 and blocks with 69: each hit it takes is cut by 28 %.

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.
