Path of Three

Search your deck for a creature card with converted mana cost 3 or less and add it to your hand, then shuffle your deck.
Scry 3 (To scry 3, look at the top three cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.)
Inside the cavern you will face three trials, and hear three prophecies. Then you will emerge, stronger.
