Marchesa, the Black Rose [Secret Lair Drop Series]

Dethrone (Whenever this creature attacks the player with the most life or tied for most life, put a +1/+1 counter on it.)
Other creatures you control have dethrone.
Whenever a creature you control with a +1/+1 counter on it dies, return that card to the battlefield under your control at the beginning of the next end step. Many of Marchesa’s subjects would die for her. In fact, most of them have.
