I logged in yesterday to find that all my self made decks, bar one, had been replaced with starter decks. I had previously deleted all starter decks and had not "built" upon them.
Same problem here. All pre-made decks are gone. What gives??
Play was restricted to training.

This is the result of the New Starter Set Cards conversion. It seems that there a still a few hiccups.
