The facts on the card
The card carries these facts from its Wikipedia article.
- Concretions are often ovoid or spherical in shape, although irregular shapes also occur.
- The word concretion is borrowed from Latin concretio ' compacting, condensing, congealing, uniting', itself derived from concrescere 'to thicken, condense, congeal', from con- 'together' and crescere 'to grow'.
- Concretions form within layers of sedimentary strata that have already been deposited.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Concretion article was read about 86,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 78 and blocks with 93: each hit it takes is cut by 37 %.
How to get Concretion
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.
