Stockpile stewardship, an Uncommon card

The card carries these facts from its Wikipedia article.

• Because no new nuclear weapons have been developed by the United States since 1992, even its youngest weapons are at least 33 years old.
• Aging weapons can fail or act unpredictably in a number of ways: the high explosives that compress their fissile material can chemically degrade, their electronic components can suffer from decay, their radioactive plutonium/uranium cores are potentially unreliable, and the isotopes used by thermonuclear weapons may be chemically unstable as well.
• Since the United States has also not tested nuclear weapons since 1992, this leaves the task of its stockpile maintenance resting on the use of simulations and applications of scientific knowledge about physics and chemistry to the specific problems of weapons aging.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Stockpile stewardship article was read about 24,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 38: each hit it takes is cut by 15 %.

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.
