Heap, an Uncommon card
In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key of P is greater than or equal to the key of C. In a min heap, the key of P is less than or equal to the key of C.

The facts on the card
The card carries these facts from its Wikipedia article.
- The heap is one maximally efficient implementation of an abstract data type called a priority queue, and in fact, priority queues are often referred to as "heaps", regardless of how they may be implemented.
- In a heap, the highest priority element is always stored at the root.
- However, a heap is not a sorted structure, it can be regarded as being partially ordered.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Heap article was read about 150,000 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 51: each hit it takes is cut by 20 %.
How to get Heap
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.
