Radio telescope, an Uncommon card

The card carries these facts from its Wikipedia article.

• Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum, just as optical telescopes are used to make observations in the visible portion of the spectrum in traditional optical astronomy.
• Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night.
• Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Radio telescope article was read about 60,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 52: each hit it takes is cut by 21 %.

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.
