The facts on the card
The card carries these facts from its Wikipedia article.
- It attenuates airborne sound-waves, reducing their amplitude, for the purposes of noise reduction or noise control.
- The energy is dissipated as heat.
- Acoustic foam is primarily made from petroleum-based polyurethane, though some types use melamine.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Acoustic foam 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 53 and blocks with 38: each hit it takes is cut by 15 %.
How to get Acoustic foam
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.
