Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Group article was read about 160,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 86 and blocks with 89: each hit it takes is cut by 36 %.
