The facts on the card
The card carries these facts from its Wikipedia article.
- Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one femtometre, which is about 0.6 times the size of a proton or neutron.
- All mesons are unstable, with the longest-lived lasting for only a few tenths of a nanosecond.
- Heavier mesons decay to lighter mesons and ultimately to stable electrons, neutrinos and photons.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Meson article was read about 130,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 81 and blocks with 70: each hit it takes is cut by 28 %.
How to get Meson
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.
