The facts on the card
The card carries these facts from its Wikipedia article.
- The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony.
- A few genera within this class live in freshwater habitats.
- Hydrozoans are related to jellyfish and corals, which also belong to the phylum Cnidaria.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hydrozoa article was read about 180,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 48: each hit it takes is cut by 19 %.
How to get Hydrozoa
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.
