Lucy in the Sky

{t}: Roll a six-sided die. On a 1, add {b}{u}{r}{g}{w} to your mana pool.
If Lucy in the Sky would be put in a graveyard from play, exile her instead. As long as Lucy in the Sky is in exile at the beginning of your upkeep, roll a die. On a 1, return Lucy in the Sky to play under your control and she gains haste. Exile her at the end of your next end step.
