The card carries these facts from its Wikipedia article.
- A surface acoustic wave is an acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decays exponentially with depth into the material, such that they are confined to a depth of about one wavelength.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Surface acoustic wave article was read about 19,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 66: each hit it takes is cut by 26 %.
How to get Surface acoustic wave
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.
