Keeper of Hollowed Misery

When Keeper of Hollowed Misery enters
the battlefield, target opponent reveals
their hand. You choose a nonland card
from it or a card from their graveyard.
Exile that card. You lose 1 life.
"In love, you become a prisoner. Yet, you don't
want to be free. In misery, you are truly free.
Yet, you desire only to be a prisoner."
