{2}{U}, {T}, Sacrifice another creature: Reveal cards from the top of your library until you reveal a nonlegendary creature card. Put that card onto the battlefield and the rest on the bottom of your library in a random order.

The List

Masters 25

Magic 2015

If your library has no nonlegendary creature cards in it, you'll reveal all the cards in your library, then put them in a random order. Although this is not technically shuffling your library, no player is allowed to know the order of those cards and you will randomize the cards in your deck.
