The top of this section has a large card viewer.

Below that is a series of filters that can be turned on or off to help you find cards for deck building. For example, you could search for all cards whose type was "Character" and whose Cost was less than "5".

You can also check the box next to "Text" to always show the card text on top of the card viewer at the top. You might want to do that if the card has errata and the text on the card image is not accurate. Or you may want to view the card text if the text on the card image just isn't readable.

The top of this section has buttons for creating, opening, and saving decks.

The "New Deck" button clears any cards from the deck list. If you have cards added already, you need to save them or they will be lost.

There are 4 different ways to load a previously made deck:
You can select the deck from the recent decks pull down menu, and then hit the "Open recent" button.
You can click the "Browse..." button and select the deck from the list of decks you have in your deck folder.
You can store a deck file online, copy the URL of the deck file, and hit the "URL" button.
You can copy the contents of a deck to your clipboard (from a deck list someone posted on a website, for example), and then hit the "Paste" button.

You can enter in the deck name and save the deck with the "Save deck" button. This will save the deck exactly as you created it, in the default .dek format.
You can also click the "Export as txt" button to make a simple text version of the deck. This simple text format just lists each card's quantity and name. The simple text format is easier to read by humans, but depending on the plugin, you may lose some information about the deck just exporting as text. A deck exported as .txt may not remember exactly what set the card you originally selected was from because the simple format only saves quantity and card name. A regular save of a deck will save all of this information.

If you click the "Copy to clipboard" button, your clipboard will be filled with your deck list (in the simple quanity and card name format) so that you can paste your deck list to another program, or post it online. (Someone could copy the result and import your deck via their "Paste" button as described above.)

Depending on how many deck zones your plugin has, you may have one or more deck zone tabs listed, starting directly under where the "New Deck" button is. A deck zone is a pile of cards you have going into a game. Some plugins have one deck zone for your main deck, another deck zone for a sideboard, or another deck zone for a "starting cards" pile. Each plugin will be different, depending on what works best for that game.
If your plugin has more than one deck zone, you can select the deck zone tab to change which subsection of the deck you are adding to. You can also drag and drop cards directly onto the deck zone tabs.

The large field is the deck list. This consists of several rows of card data. The first entry in each row is the quantity of that card in the deck list.
You can sort the deck list by clicking the column headers at the top of the deck list.

When you have an entry selected, you can use one of the five plus or minus buttons on the bottom of this section. The "+1" will increment the number of the selected card, the "+3" button will add 3 more of the selected card, and so on.
Another way to add or remove cards is to select the card in the deck list, and use the right and left arrow keys to increment and decrement it, respectively.

You can check or uncheck the Combine reprints option. When this is checked, if two cards have the same exact name but are from different sets, they will be combined together in the deck list above. The set of the first card added to the deck list will be used. If this option is not checked, your deck can have cards with the same name from different sets.

The "View tiled" button will display the contents of the deck tiled out so that all the card images can be seen. Hit the escape key or space bar to stop viewing the cards as tiled. Instead of hitting the "View tiled" button, you can just mouse over the card list and hit the space bar.

There are two ways to load the open deck to you so that you can play with it. The simple way is to just hit the "Load entire deck to you" button. This will load all deck zones to the corresponding game zones. Alternatively, you can choose to load each deck zone individually and select the destination.

This area contains the list of all cards in the game. When you add filters, you will see fewer cards listed here – just cards that pass those filters.

At the very top is a simple Search filter. This works just like a "Name begins with" filter. There is also a "Clear" button to turn off this simple filter. To turn off all of the filters affecting the cards below, you will need to hit the "Turn Filters Off" button in the Filters area.

There are two tallies listed at the top. The first shows the total number of all cards. The second shows the number of cards currently shown listed below. If you turn all filters off, these numbers should be equal. The exception to that is if your plugin includes token cards, in which case the total and shown tallies will always differ at least by the number of tokens included in the plugin.

Some plugins may have a "Format" pull down menu. A format acts as a series of predefined filters that only include certain sets that the plugin maker has defined. You can use format filters in addition to other filters in the Filters area.

Clicking the "Open Packs..." button will hide the full library of all cards and bring you to the card pool mode, where you can open virtual packs. The card pool and packs mode is further described later on this page.

There are several ways to add cards to the deck list.
At the bottom of the library of all cards area is a series of buttons that can be used to add cards to your deck list. Select a card, and then click the button to add that many to the currently selected deck zone in the deck list above. Another way to add or remove cards is to select the card in the library list and use the right and left arrow keys to increment and decrement it, respectively.

You can double click on a row in the deck list, and that card will be added to your deck list.

You can click and drag cards from your library to the deck list. While you are dragging cards, the right and left arrow keys can be used to increment and decrement, respectively, the amount of that card you are moving.

There is also the option to check "Ignoring doubles". If multiple cards pass the active filters and some of them have the same name, this option will allow you to only list one of them above. This is handy if you don't care about what set the card comes from, but only what its name is.

Lastly, the "View tiled" button works just like the "View tiled" button in the deck list section above, except that it will tile card images for all cards currently displayed in the libary list above. While viewing the card images as tiled, you can stop viewing them by hitting the escape key or space bar. Instead of hitting the "View tiled" button, you can mouse over the list of all cards and hit the space bar and that will also tile the currently visible cards.
