The facts on the card

- It is the antiparticle of the electron.
- When a positron collides with an electron, annihilation occurs.
- If this collision occurs at low energies, it results in the production of two or more 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 Positron article was read about 160,000 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 60: each hit it takes is cut by 24 %.
How to get Positron
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.
