The facts on the card
The card carries these facts from its Wikipedia article.
- This very hard, brittle, silvery-white transition metal of the platinum group is considered the second-densest naturally occurring metal, with a density of 22.56 g/cm3 as defined by experimental X-ray crystallography.
- 191Ir and 193Ir are the only two naturally occurring isotopes of iridium, as well as the only stable isotopes, the latter is the more abundant.
- It is one of the most corrosion-resistant metals, even at temperatures as high as 2,000 °C.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Iridium article was read about 300,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 82 and blocks with 100: each hit it takes is cut by 40 %.
