Abacus, a Rare card
An abacus, also called a counting frame, is a hand-operated calculating tool which was used from ancient times, in the ancient Near East, Europe, China, and Russia, until largely replaced by handheld electronic calculators, during the 1980s, with some ongoing attempts to revive their use.

Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Abacus article was read about 320,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 86: each hit it takes is cut by 34 %.
