The facts on the card
The card carries these facts from its Wikipedia article.
- Mapping of variation over an area is valuable in detecting structures obscured by overlying material.
- The magnetic variation in successive bands of ocean floor parallel with mid-ocean ridges was important evidence for seafloor spreading, a concept central to the theory of plate tectonics.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Magnetic anomaly article was read about 20,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 58: each hit it takes is cut by 23 %.
How to get Magnetic anomaly
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.
