I think wizards messed up when they previewed the token art for Masters Edition II (
http://www.wizards.com/Magic/Magazine/A ... rcana/1668). I say this because the Caribou token they show is a sketch, yet the finished art is included in Magic Online. Also included are two extra pieces of token art with very similar IDs to the other ME2 tokens. Also, I believe the art that Mahamoti D used for the "Deserter" is infact intended to be the Knight token, since it has the dimensions of a token with abilities (banding), and another piece of art definitely shows a deserter (i.e., someone dropping their weapons and running). Unaccounted for are token art for a Soldier, Graveborn, and Saproling, which I guess they use existing art for. I can't play Magic Online to confirm this, can anyone else verify any of this speculation?
Here are my renders of the tokens, as I think they should be:

And the artwork in question:
