Tree, an Uncommon card
In graph theory, a tree is an undirected graph in which every pair of distinct vertices is connected by exactly one path, or equivalently, a connected acyclic undirected graph.

Tree quiz: 3 questions
Three questions on the Tree card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
A ______ is a directed acyclic graph whose underlying undirected graph is a forest.
Answer
polyforest. A polyforest is a directed acyclic graph whose underlying undirected graph is a forest. From the Tree article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Bose–Einstein statistics. Bose–Einstein statistics 73 · Tree 69 · Aragonite 65 · Flammulina filiformis 62 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Drainage basin. Drainage basin 200,000 · Australian funnel-web spider 150,000 · Tree 91,000 · Magnoliids 66,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.
- A directed tree, oriented tree, polytree, or singly connected network is a directed acyclic graph whose underlying undirected graph is a tree.
- A polyforest is a directed acyclic graph whose underlying undirected graph is a forest.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Tree article was read about 91,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 56: each hit it takes is cut by 22 %.
How to get Tree
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.
