The facts on the card
The card carries these facts from its Wikipedia article.
- Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape.
- This is caused by seafloor spreading and continental drift, which rearranges the land and ocean.
- It has been estimated that there are 1.386 billion cubic kilometres of water on Earth.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hydrosphere article was read about 48,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 61 and blocks with 42: each hit it takes is cut by 17 %.
