The Mox Painter
Legendary Creature — Human Artist
{1}, {T}: Choose a tournament-legal Mox you don't control at random. Create a token that's a copy of it. Then if you control all ten, create a Mox Lotus token. (The ten are Amber, Chrome, Diamond, Emerald, Jet, Opal, Pearl, Ruby, Sapphire, and Tantalite. Perhaps roll a d10?)
