Sorcery
Search your library for a legendary creature card, reveal it, put it into your hand, then shuffle. Then if this spell was foretold, you may put a creature card from your hand onto the battlefield.
Foretell {4}{G}{G}{W} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
“If ever I've stood for anything to you, now is the time. All, with me! For the Rose Order!”
