The facts on the card

The card carries these facts from its Wikipedia article.

It is primarily concerned with the low-frequency, large-scale magnetic behavior of plasmas and liquid metals and has applications in multiple fields, including space physics, geophysics, astrophysics, and engineering.

Why it is Uncommon

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Magnetohydrodynamics article was read about 76,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 75: each hit it takes is cut by 30 %.
