Legend
The artist that posted it was the preeminent artist of planescape and he regularly post about D&D. He has a long history with planescape and no history (that I know of) with Magic.A quick google search told me that this image is related to MTG Dragons of Tarkir. Not sure where the Planescape speculation is coming from.
EDIT: To clarify, his "old pals" at WotC would be D&D people, not Magic people.
