Options: Deck Overlay

Enabling the Show deck overlay when match stats option will display the 'deck overlay' popup when a match starts. This contains a list of the cards in your deck which you can use to remember what you've played during this match. Click on a card to mark it as used, right-click to unmark it.

The uploader gets the list of cards from HearthStats.net, so if you haven't listed the cards in your deck on HearthStats.net then the popup won't appear. Log in to [HearthStats.net][HearthStats.net] to set up your decks first.

Note that the deck overlay is for constructed play, and it not yet supported in arena mode.
