Jeanne's Masterpiece

When Jeanne's Masterpiece enters the battlefield, draw two cards, then discard a card. When Jeanne's Masterpiece leaves the battlefield, if you control a Jeanne Planeswalker, return it to the battlefield tapped. Otherwise, exile it.
'She is my masterpiece, the perfect Figment of my mind!'
