The facts on the card
The card carries these facts from its Wikipedia article.
- This age corresponds to the final stages of Earth's accretion and planetary differentiation during the early Hadean eon.
- Estimates are based on radiometric dating of meteoritic material, the ages of which are approached by those of the oldest-known terrestrial material and lunar samples, and accretion models consistent with observations of planet formation in protoplanetary disks.
- Following the development of radiometric dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Age of Earth article was read about 210,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 78: each hit it takes is cut by 31 %.
How to get Age of Earth
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.
