The facts on the card
The card carries these facts from its Wikipedia article.
- Various different reference ellipsoids have been used as approximations.
- It is an oblate spheroid whose minor axis, connecting the geographical poles, is approximately aligned with the Earth's axis of rotation.
- The ellipsoid is also defined by the major axis, the difference between the two axes is slightly more than 21 km or 0.335%.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Earth ellipsoid article was read about 26,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 50: each hit it takes is cut by 20 %.
How to get Earth ellipsoid
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.
