I have created a deck tracker for Faeria. It is designed for Windows only at the moment and for the English client. It currently only has its core functionality which is keeping track of what cards are left in your deck.
In the future I will add deck statistics and card probability to the interface. Also, I’m thinking about hooking up a database and showing the most common/highest win rate decks.
You can download it for free at http://faeriadecktracker.com/
Lastly, the tracker tends to break with new updates but I will update the program to work with each patch.
