The facts on the card
The card carries these facts from its Wikipedia article.
- It contains only the four elements titanium, zirconium, hafnium, and rutherfordium.
- The group is also called the titanium group or titanium family after its lightest member.
- As is typical for early transition metals, zirconium and hafnium have only the group oxidation state of +4 as a major one, and are quite electropositive and have a less rich coordination chemistry.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Group 4 element article was read about 14,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 75: each hit it takes is cut by 30 %.
