With the Deck Manager and the Deck Editing options, you'll be able to administrate all your constructed Decks in The Horus Heresy: Legions. To access it, click in the "Cards" button in the game main HUD. This will open the following window:

From the first tab you'll be able to edit your current equipped Deck, while in the second you'll manage (create, delete or copy) all of them. The Collection tab will be skipped as it pertain to its own page.
Deck Managing[]
With the "Change Deck" option, you can view all of your Decks:

As you can see, is divided in:
- A constructed Deck, displaying the chosen Warlord and Faction. If it glows, it means it's the current equipped one.
- Move the position of the selected Deck (left or right).
- Jump to the last or first Deck on the list.
- Paste the code of a Deck to build it on the list. While it will show the full Deck, it won't display the cards you are missing, so you'll have to check after to see if you can play it (you will have to replace the missing cards with others to make it playable).
- Copy the current equipped Deck. An editing window will open where you can change cards if you want. If you don't change the name of this copied Deck, a "+" will appear beside the name.
- Delete the current selected Deck (this cannot be undone, so be careful).
- Filter your Decks by name or categories (see below).
- Name of the Deck. You can change it to better exemplified what is about, or leave it as it is (being named after the chosen Warlord).
- Special category equipped (see below).
- Create a new Deck (will always be the last option).
- Close and return to the previous window.
You can scroll up or down to see the full list, and you can have up to 30 constructed Decks.
When selecting any Deck in this window, an option to "Edit" or "View" will appear above them.

—Categories[]
Beside the usual "Faction" categories, there are special ones you can use to better differentiate your Decks.
The "original" names don't really matter in the general sense, so you can use them however you see fit (divide all Decks of the "Aggro" Archetype with the "Speartip" one, all your main Decks with the "Specialized" one, etc.). Click in the empty space (the option [9] in the image) to select your preferred category.

- Change the Deck name.
- View the Deck.
- The cards placed in the Deck.
- Filter by categories (image on the right).
- Display the text of the card in this window (without the need to click on the card).
