Sorcery - Revelation
Look at the top three cards of target player's library. Put one back and exile the rest.
Coalesce {5}{U} (You may cast this from your graveyard for {5}{U}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
Whenever Lurk at Vision's Edge attacks, defending player exiles the top five cards of their library.
