Planetary core, an Uncommon card

The card carries these facts from its Wikipedia article.

• Cores may be entirely liquid, or a mixture of solid and liquid layers as is the case in the Earth.
• In the Solar System, core sizes range from about 20% to 85% of a planet's radius.
• Gas giants also have cores, though the composition of these are still a matter of debate and range in possible composition from traditional stony/iron, to ice or to fluid metallic hydrogen.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Planetary core article was read about 27,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 76: each hit it takes is cut by 30 %.

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.
