A few years ago I programmed the “Ultimate Warlord Online Deck Builder” - UWODB (in case you wonder, the “most common” pronounciation is “uwodib”). The idea was not only to provide a database to look for cards via the usual methods (class, level, type, faction, etc.), but to also catalogue them with a host of special traits, for example cards that use orders, produce ranged strikes or draw cards.

What I personally found very helpful was that as a registered player you could also save the cards you looked for to a deck, then tweak the deck and print it either as a deck list (to take to a tournament, or just to copy & paste to a forum or into an e-mail) or - in my eyes the best feature of all - print printer-friendly proxy cards that you could sleeve to test new deck ideas.
This system is now being overhauled. The main difference now is that it is tied into the Warlord-Forum at www.cardmasters.de . As a normal user you will find a complete database of all play-legal 4E cards. As a member of the Ordo Phoenicis Ascendentis you will have automatic access to the deckbuilding and printing features, as well as commenting on cards (comments that others can see).
The changes necessary to make this possible require a full reset of all decks, though.
So if you are still using UWODB and would like to keep the decks you created in there for reference - please print them out or otherwise save them!
Within the next three days I will delete the decks and get the new UWODB beta online.
