The facts on the card
The card carries these facts from its Wikipedia article.
- It is a generalization of a plane, but, unlike a plane, it may be curved.
- An example of a non-flat surface is the sphere.
- There are several more precise definitions, depending on the context and the mathematical tools that are used for the study.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Surface 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 44: each hit it takes is cut by 18 %.
How to get Surface
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.
