Some previous Magic sets feature double-faced cards, which have a Magic card face on each side rather than a Magic card face on one side and a Magic card back on the other. If a double-faced card is manifested, it will be put onto the battlefield face down. While face down, it can't transform. If the front face of the card is a creature card, you can turn it face up by paying its mana cost. If you do, its front face will be up. Although a double-faced card can enter the battlefield face down, one already on the battlefield can't be turned face down.
