Malachite, an Uncommon card

The card carries these facts from its Wikipedia article.

• This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
• Individual crystals are rare, but occur as slender to acicular prisms.
• Pseudomorphs after more tabular or blocky azurite crystals also occur.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Malachite article was read about 170,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 71: each hit it takes is cut by 28 %.

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.
