All the details about the chosen deck are shown on the Deck Page. At the top, you can see its author, its name, and any description or comment the author assigned to it when he/she created it. You also have links to the different sections and activities of the deck page: distribution of cards [Statistics], discussion [Discuss], and rating [Rate]. If you are the author of the deck that you are viewing, then you will also have a link that will let you modify it [Edit].
Next, you have the list of cards included in the deck. For each card, the number of copies of it in the deck is shown, together with some basic data like the set it comes from, its number in that set, the type of card and its rarity. The name of the card is also a link which opens a window with all the details about that card.
The listing of cards is initially grouped in sections, if the corresponding game has them, but you can choose to group the cards by other parameters, like their rarity, type, etc., by selecting them from the drop-down list located at the top, next to "Group cards by". This way you can study in detail what types of cards compose the deck; for example, which ones are rare and which ones uncommon. For each group you get the total of cards for that group in the deck.
You can also see the list in an extended format which shows all the details about each card, including its image and game text, if they are available. It is like having the page of details for all the cards shown at the same time. To access this information you only need to click on the link at the upper right corner of the Deck Page, where it reads "extended format". You can see the standard format again from the corresponding link in the new page.
Under the list of cards there is the Statistics section, which analyzes the deck, giving all the information about the distribution of its cards by rarities, types, and other parameters of the game. This way you can see at once if most of the cards in that deck are rare, for example, or if there are many of a given type (or clan, or culture, or color). For each parameter, you get a bar diagram showing graphically the percentages, and you also see the number of cards and the corresponding percentage as numeric values.
In this section you have the chance to vote for the deck and indicate how good you think it is. Having into account whether you think it follows a correct strategy that will let it win the game, whether it has the appropriate cards in the best proportions, and whether you think it would be difficult to beat or not, you should give it a score from 1 to 5, where 1 is the worst rating, for bad, not well-thought decks, and 5 is the best rating, for decks that are really well designed.
If you have already voted for this deck at some point (or if it is your deck and therefore can not vote for it), you will be able to see in this section the current score obtained by this deck, with a sliding bar that shows graphically that score in relation to the minimum and maximum values.
The last section in the Deck Page is the discussion about it, in which all users of the web may publish their comments about the deck, give their opinion, and discuss its pros and cons.
This section works much like the forums, showing the messages together with the name of the user who wrote them and the date in which they did, and allowing you to add your comments (through the "Add your comments" links) and to include a reference to another existing one (through the "quote" button).
You can also subscribe to the discussion, so that you get a notice by e-mail as soon as someone adds a new comment. This is the best way to stay up to date with the conversation, and to learn about strategy and deck building.
