Luna Lumarian

Flash, First Strike, Shroud, Deathtouch.
When LuLu deals combat damage to a player,
look at his or her hand. You may exile a
noncreature spell from their hand or graveyard.
For as long as you control LuLu, you may cast
spells exiled this way. Exiled spells cost {1} less to cast.
"Just as quickly and quietly as she appeared, she had gone, with many of my dice in tow..."
