- The effect is due to the low ignition temperature of cerium, between 150 and 180 °C.
- Ferrocerium has many commercial applications, such as the ignition source for cigarette or cigar lighters, strikers for gas welding and cutting torches, deoxidization in metallurgy, and ferrocerium rods.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ferrocerium article was read about 42,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 50 and blocks with 31: each hit it takes is cut by 12 %.
