Since Craterhoof Behemoth has long been a valuable asset to Commander players, you can bet that it will maintain a high value even when this set cycles out of Standard
Furthermore, Magic is releasing a two-player Starter Set with Cloud, Planets Champion and Sephiroth, Planets Heir as the featured cards
