Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Capacitor article was read about 330,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 88 and blocks with 84: each hit it takes is cut by 34 %.
How to get Capacitor
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.
