Cryptanalysis, an Uncommon card

The card carries these facts from its Wikipedia article.

• Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
• In addition to mathematical analysis of cryptographic algorithms, cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation.
• Even though the goal has been the same, the methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity, ranging from the pen-and-paper methods of the past, through machines like the British Bombes and Colossus computers at Bletchley Park in World War II, to the mathematically advanced computerized schemes…

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cryptanalysis article was read about 54,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 63: each hit it takes is cut by 25 %.

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.
