Kernel, a Rare card

The card carries these facts from its Wikipedia article.

• The kernel is also responsible for preventing and mitigating conflicts between different processes.
• It is the portion of the operating system that is always resident in memory and facilitates interactions between hardware and software components.
• A full kernel controls all hardware resources via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the use of common resources, such as CPU, cache, file systems, and network sockets.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Kernel article was read about 280,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 83 and blocks with 77: each hit it takes is cut by 31 %.

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.

The cards just above and just below Kernel in the power ranking, all domains together.
