The Doctor Who Commander deck Master of Evil includes 1 ready-to-play blue-black-red deck with 100 Magic cards (2 legendary creatures as traditional foil cards, 98 non-foil cards), 10 Planechase cards, 1 six-sided world cube, a collectible booster sample pack of 2 cards (which includes 2 traditional foil cards or non-foil cards with special card printing, including 1 common or not-so-common card and 1 card of rarity rare or higher), 1 display commander card as an Etched Foil card (a copy of the commander card made of cardboard with textured foil effect on the card edge and illustration), 10 double-sided token cards, 1 deck box (with space for 100 cards including sleeves), 1 life point wheel, 1 strategy supplement, and 1 rules reference card
