Interplanar Gateways

Choose and reveal a card from your hand: Shuffle your library, then reveal cards from the top of your library until you reveal a card with the same types and converted mana cost as the card you chose. Put that card into your hand, then shuffle the chosen card and the revealed cards into your library. Any player may activate this ability only as a sorcery. (For example, if you chose a non-legendary artifact creature, you may only get a non-legendary artifact creature in this way.)
