The facts on the card
The card carries these facts from its Wikipedia article.
- Reefs are formed of colonies of coral polyps held together by calcium carbonate.
- Most coral reefs are built from stony corals, whose polyps cluster in groups.
- Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Coral reef article was read about 250,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 92 and blocks with 95: each hit it takes is cut by 38 %.
