CP violation, an Uncommon card

The card carries these facts from its Wikipedia article.

• CP-symmetry states that the laws of physics should be the same if a particle is interchanged with its antiparticle while its spatial coordinates are inverted.
• CP violation is only observed in the weak interaction.
• The discovery of CP violation in 1964 in the decays of neutral kaons resulted in the Nobel Prize in Physics in 1980 for its discoverers James Cronin and Val Fitch.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The CP violation article was read about 81,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 64: each hit it takes is cut by 26 %.

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.
