Boron, a Rare card

The card carries these facts from its Wikipedia article.

• In its crystalline form it is a brittle, dark, lustrous metalloid, in its amorphous form it is a brown powder.
• As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride.
• Boron is synthesized entirely by cosmic ray spallation and supernovas and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Earth's crust.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Boron article was read about 310,000 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 87: each hit it takes is cut by 35 %.

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.
