Q: What type of card is Missy?

Missy is a Legendary Creature — Time Lord Rogue. Its oracle text reads: "Whenever another nonartifact creature dies, return it to the battlefield under your control face down and tapped. It's a 2/2 Cyberman artifact creature. At the beginning of your end step, each opponent faces a villainous choice — Each artifact creature you control deals 1 damage to that opponent, or you draw a card and chaos ensues."
