The list of cards you see on the right side of the screen is divided between the card pool (top) and your deck (at the bottom). Above that are multiple filters to narrow down your search. The text search uses the name, type, subtype and the full card text, so you can even search for certain abilities.
To add or remove cards, select one or more cards and use the buttons on the bottom left. Alternatively you can double-click a card in the card pool to add it to your deck or double-click a card in your deck to remove it. Double-clicking using the right mouse button on a card in your deck will add another copy of it.
A deck needs to be compliant with the following rules or you will not be able to use it:
- The minimun deck size is 40.
- A deck may contain no more than 4 copies of any named card, with the exception of "basic lands".
Just as on the Deck View screen, the Duel menu allows you to load or save a deck.
Once you've finished constructing your deck, you can start the game by chosing 'Play game' from the Duel menu, or click the 'Close' button to go back to the Deck View screen.
