Queen Icharopatra

Flying

Whenever another nontoken creature you control dies, manifest dread. (Look at the top two cards of your library. Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it’s a creature card.)

Descend 4 —Whenever a permanent you control is turned face up, if there are four or more permanents in your graveyard, create a 2/2 white and black Harpy creature token with flying and lifelink.
