The facts on the card
The card carries these facts from its Wikipedia article.
- In fluid dynamics, the field is the fluid velocity field.
- In electrodynamics, it can be the electric or the magnetic field.
- The term circulation was introduced by William Thomson in 1869 to denote the line integral of velocity around a closed curve as a kinematic measure of rotational motion in a fluid, independent of any particular application.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Circulation article was read about 12,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 54 and blocks with 30: each hit it takes is cut by 12 %.
How to get Circulation
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.
