Here's my quick list of notable reprints for Commander: White: Ghostly Prison Blue: Show and Tell, Desertion Black: Phyrexian Arena (new art!) Red: Gratuitous Violence Green: Beast Within, Berserk, Birds of Paradise, Burgeoning, Explosive Vegetation Colorless: Horn of Greed (first foil printing!) Multicolor: Exotic Orchard Next Up: Budget Commander
