Cybernetics, a Rare card

The card carries these facts from its Wikipedia article.

• It is concerned with general principles that are relevant across multiple contexts, including engineering, ecological, economic, biological, cognitive and social systems and also in practical activities such as designing, learning, and managing.
• Cybernetics' transdisciplinary character means that it intersects with a number of other fields, resulting in a wide influence and diverse interpretations.
• The field is named after an example of circular causal feedback, that of steering a ship.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cybernetics article was read about 260,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 75: 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.
