When Killer's Mask enters, 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 their graveyard. Turn it face up any time for its mana cost if it's a creature card.), then attach Killer's Mask to that creature.
Equipped creature has menace (This creature can't be blocked except by two or more creatures.).
Equip (: Attach to target creature you control. Equip only as a sorcery. This card enters the battlefield unattached and stays on the battlefield if the creature leaves.)
