- In an aqueous solution, chromate and dichromate ions can be interconvertible.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Chromate and dichromate article was read about 25,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 59 and blocks with 51: each hit it takes is cut by 20 %.
