Gravity anomaly, an Uncommon card

The card carries these facts from its Wikipedia article.

• If the Earth were an ideal oblate spheroid of uniform density, then the gravity measured at every point on its surface would be given precisely by a simple algebraic expression.
• However, the Earth has a rugged surface and non-uniform composition, which distorts its gravitational field.
• The theoretical value of gravity can be corrected for altitude and the effects of nearby terrain, but it usually still differs slightly from the measured value.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gravity anomaly article was read about 64,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 64 and blocks with 65: each hit it takes is cut by 26 %.

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.
