The facts on the card
The card carries these facts from its Wikipedia article.
- If a and b are different, then is different from.
- In contrast, the unordered pair {a,b} always equals the unordered pair {b,a}.
- Ordered pairs are also called 2-tuples, or sequences of length 2.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ordered pair article was read about 30,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 45: each hit it takes is cut by 18 %.
How to get Ordered pair
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.
