In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- A formal grammar describes how to form strings from a formal language's alphabet that are valid according to the language's syntax.
- The linguist Noam Chomsky theorized that four different classes of formal grammars existed that could generate increasingly complex languages.
- Each class can also completely generate the language of all inferior classes.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Chomsky hierarchy article was read about 120,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 61 and blocks with 34: each hit it takes is cut by 14 %.
How to get Chomsky hierarchy
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.
