The facts on the card
The card carries these facts from its Wikipedia article.
- It contrasts with the more common alternating current transmission systems.
- HVDC lines are commonly used for long-distance power transmission, since they require fewer conductors and incur less power loss than equivalent AC lines.
- HVDC also allows power transmission between AC transmission systems that are not synchronized.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The High-voltage direct current article was read about 94,000 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 68: each hit it takes is cut by 27 %.
How to get High-voltage direct current
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.
