Particle accelerator, an Uncommon card

The card carries these facts from its Wikipedia article.

• Small accelerators are used for fundamental research in particle physics.
• Accelerators are also used as synchrotron light sources for the study of condensed matter physics.
• Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion implanters for the manufacture of semiconductors, and accelerator mass spectrometers for measurements of rare isotopes such as radiocarbon.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Particle accelerator article was read about 190,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 72: each hit it takes is cut by 29 %.

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.
