The Elemental Thunder Deck from Planechase has a unique John Avon Forest, similar but not the same as his M10 Forest. Is it possible that WotC had paid for the piece but couldn't fit it into M10? Or could this also be a preprint from Zendikar? It's the only extra land art I found in the decks.
I found it in 7th Edition. Sorry guys (closer down.)
BTW, I had a hard time locating all versions of art from a specific artist using Magiccardinfo and gatherer. I didn't think the filters would be so obtuse.
