The Unknown

At the begining of your end step 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.)
When The Unknown enters, manifest it and manifest dread twice secretly. (Put it onto the battlefield face down as a 2/2 creature. Turn it face
up any time for its mana cost if it's a creature card.)
