Chlorine, a Rare card

The card carries these facts from its Wikipedia article.

• The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them.
• Chlorine is a yellow-green gas at room temperature.
• It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only oxygen and fluorine.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Chlorine article was read about 340,000 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 94: each hit it takes is cut by 38 %.

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.
