It appears that several parallax land styles have turned to the non-parallax style. I have noticed specifically my Theroes lands for example, and others have mentioned the fetch lands as well. You can see in the first picture that I have "favorited" (with the heart) the parallax style and the deck builder shows that the parallax style is in the deck. I have attached the second pic showing the non-parallax style. So essentially I have two NON-parallax style Theroes plains and the parallax one is gone.
