I've held off on buying this one as I've read it's riddled with problems, especially losing your decks.
Personally, my favorite part of the game is spending the time unlocking them all (have over 100 hours in on 2012) and I could care less if it becomes outdated as far as multiplay in a month. I can play IRL if I want to multiplay.
SO, long story short... have they fixed the disappearing cards bugs... that's really my MAJOR concern... I can live with other minor ones.
