The facts on the card
The card carries these facts from its Wikipedia article.
- The Kelvin scale is an absolute temperature scale that starts at the lowest possible temperature, taken to be 0 K. By definition, the units of the Celsius scale and the Kelvin scale have the same magnitude, and any temperature in degrees Celsius can be converted to the kelvin scale by adding 273.15.
- The 19th-century British scientist Lord Kelvin first developed and proposed the scale.
- It was often called the "absolute Celsius" scale in the early 20th century.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Kelvin article was read about 310,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 90: each hit it takes is cut by 36 %.
How to get Kelvin
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.
