Ideal gas, an Uncommon card

The card carries these facts from its Wikipedia article.

• The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics.
• The requirement of zero interaction can often be relaxed if, for example, the interaction is perfectly elastic or regarded as point-like collisions.
• Under various conditions of temperature and pressure, many real gases behave qualitatively like an ideal gas, where the gas molecules play the role of the ideal particles.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ideal gas article was read about 53,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 41: each hit it takes is cut by 16 %.

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.
