Index -> Interface -> Deck Builder -> Limited Deck Builder
When you participate in a Sealed or Draft tournament, you will use a special version of the Deck Builder to construct and modify your deck. It is similar to the normal Deck Builder, though you will only have access to the cards available to you in that tournament. You cannot use the Open/Add, Save As, Open Online, Save As Online, or Delete functions in the Limited Deck Builder.
Before the first round of the tournament begins, you'll have a fixed amount of time to construct your deck. The time remaining to you will be displayed at the top of the screen. When you complete your deck, click the Save Deck button near this timer to signal you are ready to begin. If there is an error with your deck, your deck will not be saved, and the Deck Validator will open to explain the error.
Between rounds of the tournament, you may return to the Limited Deck Builder by clicking on the Deck Builder tab on the right hand side of the screen. If you finish a round early, you may use the extra time you have to make modifications to your deck. (Again, you are limited to the cards you can access during the tournament.
