Power 126 (ATK + DEF): stronger than 60 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is defined as one particular definite integral of the ratio between an exponential function and its argument.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Exponential integral article was read about 51,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 66 and blocks with 60: each hit it takes is cut by 24 %.
How to get Exponential integral
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.
