The facts on the card
The card carries these facts from its Wikipedia article.
- A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering.
- Other uses include clocks and analogue computers.
- Differentials can also provide a gear ratio between the input and output shafts.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Differential article was read about 79,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 52: each hit it takes is cut by 21 %.
How to get Differential
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.
