Magnesium, a Rare card

The card carries these facts from its Wikipedia article.

• It is a shiny gray metal having a low density, low melting point, and high chemical reactivity.
• Like the other alkaline earth metals, it occurs naturally only in combination with other elements and almost always has an oxidation state of +2.
• It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Magnesium article was read about 330,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 83 and blocks with 98: each hit it takes is cut by 39 %.

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.
