Rule 701.40a
Official source text from the 25 July 2025 Rules release
To manifest a card, turn it face down. It becomes a 2/2 face-down creature card with no text, no name, no subtypes, and no mana cost. Put that card onto the battlefield face down. That permanent is a manifested permanent for as long as it remains face down. The effect defining its characteristics works while the card is face down and ends when it’s turned face up.
