Instability quiz: 3 questions
Three questions on the Instability card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word

Answer
deflections. Beyond a certain threshold, structural deflections magnify stresses, which in turn increases deflections. From the Instability article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Robert B. Leighton. Robert B. Leighton 59 · Instability 55 · Kenjiro Takayanagi 52 · Extrusive rock 48 ATK in WikiCards.
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.
- Not all systems that are not stable are unstable, systems can also be marginally stable or exhibit limit cycle behavior.
- In structural engineering, a structural beam or column can become unstable when excessive compressive load is applied.
- Beyond a certain threshold, structural deflections magnify stresses, which in turn increases deflections.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Instability article was read about 7,700 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 31: each hit it takes is cut by 12 %.
How to get Instability
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.
