- This is the only U.S. reactor accident to have caused immediate deaths.
- Part of the Army Nuclear Power Program, SL-1 was a prototype for reactors intended to provide electrical power and heat for small, remote military facilities, such as radar sites near the Arctic Circle, and those in the DEW Line.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The SL-1 article was read about 410,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 96: each hit it takes is cut by 38 %.
How to get SL-1
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.
