The facts on the card

The card carries these facts from its Wikipedia article.

Springs can store energy when compressed, when extended, and/or when twisted.
In everyday use, the term most often refers to coil springs, but there are many different spring designs.
Modern springs are typically manufactured from spring steel.

Why it is Uncommon

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Spring 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 68 and blocks with 61: each hit it takes is cut by 24 %.

How to get Spring

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.
