Symbiosis, an Uncommon card

The card carries these facts from its Wikipedia article.

• In 1879, Heinrich Anton de Bary defined symbiosis as "the living together of unlike organisms".
• The term is sometimes more exclusively used in a restricted, mutualistic sense, where both symbionts contribute to each other's subsistence.
• This means that they benefit each other in some way.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Symbiosis article was read about 180,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 91: each hit it takes is cut by 36 %.

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.
