The facts on the card
The card carries these facts from its Wikipedia article.
- The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.
- The existence of magnetars was proposed in 1992 by Robert Duncan and Christopher Thompson, who sought to explain the properties of transient sources of gamma rays, now known as soft gamma repeaters.
- Over the following decade, the magnetar hypothesis became widely accepted, and was extended to explain anomalous X-ray pulsars.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Magnetar article was read about 150,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 70: each hit it takes is cut by 28 %.
How to get Magnetar
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.
