The facts on the card
The card carries these facts from its Wikipedia article.
- In this case, a massive star collapses to form a rotating black hole emitting twin astrophysical jets and surrounded by an accretion disk.
- It is a type of stellar explosion that ejects material with an unusually high kinetic energy, an order of magnitude higher than most supernovae, with a luminosity at least 10 times greater.
- Hypernovae release such intense gamma rays that they often appear similar to a Type Ic supernova, but with unusually broad spectral lines indicating an extremely high expansion velocity.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hypernova article was read about 57,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 64 and blocks with 39: each hit it takes is cut by 16 %.
How to get Hypernova
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.
