Facilitated diffusion, an Uncommon card

The card carries these facts from its Wikipedia article.

• Being passive, facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport step itself, rather, molecules and ions move down their concentration gradient according to the principles of diffusion.
• Facilitated diffusion differs from simple diffusion in several ways: The transport relies on molecular binding between the cargo and the membrane-embedded channel or carrier protein.
• The rate of facilitated diffusion is saturable with respect to the concentration difference between the two phases, unlike free diffusion which is linear in the concentration difference.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Facilitated diffusion article was read about 21,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 60 and blocks with 43: each hit it takes is cut by 17 %.

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.
