The facts on the card
The card carries these facts from its Wikipedia article.
- In other words, it is the set of c for which the sequence f c, f c, and so on, remains bounded in absolute value.
- This set was first defined and drawn by Robert W. Brooks and Peter Matelski in 1978, as part of a study of Kleinian groups.
- Afterwards, in 1980, Benoit Mandelbrot obtained high-quality visualizations of the set while working at IBM's Thomas J. Watson Research Center in Yorktown Heights, New York.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Mandelbrot set article was read about 440,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 84: each hit it takes is cut by 34 %.
How to get Mandelbrot set
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.
