This tool is designed to help you craft the perfect Hearthstone deck to take down your opponents in ranked or casual play. The in-game collection manager in the Hearthstone app only allows a player to filter through cards by mana cost and by text search. This is great if you already know the card that you are looking for, but not as helpful for exploring and discovering new cards to craft and add to your deck. With this tool you can easily filter by card mechanic, race, class, card type etc. and get a visual display of things like number of murloc cards available to a Paladin or which classes have weapons available to them to easily answer all your deck crafting queries.
