I wanted to offer this up to the deckbox community. I have made a torrent containing all the widescreen wallpapers from Daily MTG from Stone Rain onward, largely for my own guild, but I invite everyone to share.

I might make torrents for the other sizes if it suits me, or if people request a size that's available from WotC.

Edit: And it would appear that the forum won't accept the file, so here's a link to our guild's Google Group post concerning the torrent.

Wow! Thanks man, that's delish! :)
