The facts on the card
The card carries these facts from its Wikipedia article.
- It is produced artificially in nuclear reactors through neutron activation of 59Co.
- Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur.
- In the latter case, the incidentally produced 60Co is largely the result of multiple stages of neutron activation of iron isotopes in the reactor's steel structures via the creation of its 59Co precursor.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cobalt-60 article was read about 130,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 71: each hit it takes is cut by 28 %.
How to get Cobalt-60
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.
