This area lets you control the way the Deck Builder works.
Deck Builder Display
Filter Default: Setting this to "Default to all fiters off (empty)" means that by default the deckbuilder will not show any cards when you first enter it, or when you select the reset button. Selecting "Default to all culture filters on" means that all cards will be displayed by default.
Ownership Default: Setting this to "Default to only show cards I own" means that only cards that you own will show up in the deckbuilder. If you would like to see cards that you don't own as well, select "Default to showing all cards."
