The facts on the card
The card carries these facts from its Wikipedia article.
- Previously a 4th-magnitude star, it brightened in 1837 to become brighter than Rigel, marking the start of its so-called "Great Eruption".
- It became the second-brightest star in the night sky between 11–14 March 1843 before fading well below naked-eye visibility after 1856.

Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Eta Carinae 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 89 and blocks with 95: each hit it takes is cut by 38 %.
How to get Eta Carinae
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.
