Looking for a certain avatar artwork from one of the Duels games

I'm absolutely certain there was a selectable player avatar in one of the Duels of the Planeswalkers games that depicted a mage, probably some sort of Dimir guildmage, in a black cloak and hood, conjuring a key using blue mana. I don't remember which iteration of DotP it was in.

I can't find the image ANYWHERE. I'm reasonably certain it hasn't been used on any card art but Google doesn't help either. I don't particularly feel like re-installing DotP year by year, so my hope's on Reddit coming through.

Anyone remember this avatar or has my memory been messed with by the House?
