The facts on the card
The card carries these facts from its Wikipedia article.
- During this time, the remaining sunlight takes on a mostly blue shade.
- This shade differs from the colour of the sky on a clear day, which is caused by Rayleigh scattering.
- The blue hour occurs when the Sun is far enough below the horizon so that the sunlight's blue wavelengths dominate due to the Chappuis absorption in the ozone layer.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Blue hour article was read about 83,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 51 and blocks with 46: each hit it takes is cut by 18 %.
How to get Blue hour
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.
