Suppose I have played The Prismatic Bridge (the back face of Esika, God of the Tree), an enchantment which has "At the beginning of your upkeep, reveal cards from the top of your library until you reveal a creature or planeswalker card. Put that card onto the battlefield and the rest on the bottom of your library in a random order."
Now suppose that the card revealed this way is Valki, God of Lies - which is a double-faced card with Tibalt, Cosmic Imposter on the back. Can I put Tibalt, Cosmic Imposter into play instead of Valki?
