The facts on the card
The card carries these facts from its Wikipedia article.
- It usually refers to the extent to which a pair of quantities are linearly related.
- More generally, an arbitrary relationship between variables is called an association, meaning the degree to which the variability in one can be accounted for by the other.
- The presence of a correlation is not sufficient to infer the presence of a causal relationship, and this is often stated as "correlation does not imply causation".
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Correlation article was read about 170,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 73 and blocks with 58: each hit it takes is cut by 23 %.
How to get Correlation
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.
