Lady Maria

First Strike, Haste, Vileblood (you can bring this creature back from your graveyard to the battlefield
under your control by paying 5 life)
Whenever Lady Maria enters the battlefield, you
may search in your library or graveyard for a card called Astral Clocktower and put it in your hand.
"A corpse... should be left well alone. Only an honest
death will cure you now."
