Inescapable Nightmares

Enchant creature
When Inescapable Nightmares enters the battle-
field attached to a creature, tap that creature.
Enchanted creature doesn't untap during its
controller's untap step unless they mill three
cards. If they don't untap enchanted creature
during their untap step, they lose 1 life.
Deep asleep or wide awake... even you will break.
