The facts on the card
The card carries these facts from its Wikipedia article.
- This definition can be recalled by using the mnemonic CCD for cathode current departs.
- Conventional current describes the direction in which positive charges move.
- Electrons, which are the carriers of current in most electrical systems, have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow: this means that electrons flow into the device's cathode from the external circuit.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cathode article was read about 58,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 58: each hit it takes is cut by 23 %.
How to get Cathode
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.
