The facts on the card
The card carries these facts from its Wikipedia article.
- That is, the group operation is commutative.
- With addition as an operation, the integers and the real numbers form abelian groups, and the concept of an abelian group may be viewed as a generalization of these examples.
- Abelian groups are named after the Norwegian mathematician Niels Henrik Abel.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Abelian group article was read about 95,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 46: each hit it takes is cut by 18 %.
How to get Abelian group
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.
