Cambrian, a Rare card

The card carries these facts from its Wikipedia article.

• The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran Period 538.8 Ma to the beginning of the Ordovician Period 486.85 Ma.
• Most of the continents were located in the southern hemisphere surrounded by the vast Panthalassa Ocean.
• The assembly of Gondwana during the Ediacaran and early Cambrian led to the development of new convergent plate boundaries and continental-margin arc magmatism along its margins that helped drive up global temperatures.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cambrian article was read about 450,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 88 and blocks with 100: each hit it takes is cut by 40 %.

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.
