Orientability, an Uncommon card
In mathematics, orientability is a property of some topological spaces such as real vector spaces, Euclidean spaces, surfaces, and more generally manifolds that allows a consistent definition of "clockwise" and "anticlockwise".

The facts on the card
The card carries these facts from its Wikipedia article.
- It generalizes the concept of curve orientation, which for a plane simple closed curve is defined based on whether the curve interior is to the left or to the right of the curve.
- A space is orientable if such a consistent definition exists.
- In this case, there are two possible definitions, and a choice between them is an orientation of the space.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Orientability article was read about 35,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 45: each hit it takes is cut by 18 %.
How to get Orientability
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.
