Petroleum, an Epic card

The card carries these facts from its Wikipedia article.

• The term petroleum refers to both naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
• Petroleum is a fossil fuel formed over millions of years from anaerobic decay of organic materials from buried prehistoric organisms, particularly plankton and algae.
• It is estimated that 70% of the world's oil deposits were formed during the Mesozoic, 20% were formed in the Cenozoic, and only 10% were formed in the Paleozoic.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Petroleum article was read about 610,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 89 and blocks with 70: each hit it takes is cut by 28 %.
