- Based on analysis by French physicist Augustin-Jean Fresnel, they are sometimes called Fresnel zone plates in his honor.
- The zone plate's focusing ability is an extension of the Arago spot phenomenon caused by diffraction from an opaque disc.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Zone plate article was read about 14,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 56 and blocks with 43: each hit it takes is cut by 17 %.
How to get Zone plate
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.
