MTG Studio supports OPT now.

I talked to Gaddlord and he agreed to add support for OPT decks into his deckbuilder/collection management software. http://www.mtgstudio.com/


It costs some cash but has a demo you can try out. I've got a decent sized collection and found it to be indispensable. Obviously it's something that you want to try out for yourself to see if you'd be willing to put any money into it.
