The facts on the card
The card carries these facts from its Wikipedia article.
- The changes are controlled by a code known to both transmitter and receiver.
- FHSS is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access communications.
- The frequency band is divided into smaller sub-bands.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Frequency-hopping spread spectrum article was read about 57,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 61 and blocks with 37: each hit it takes is cut by 15 %.
How to get Frequency-hopping spread spectrum
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.
