The card carries these facts from its Wikipedia article.
- The process is known as rectification, since it "straightens" the direction of current.
- Physically, rectifiers take a number of forms, including vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium oxide plates, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches.
- Historically, even synchronous electromechanical switches and motor–generator sets have been used.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Rectifier article was read about 120,000 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 57: each hit it takes is cut by 23 %.
How to get Rectifier
