Celestial Observatory

{1}, {t}: Search your library for a basic land card, reveal it, put it into your hand, then shuffle your library. If Celestial Observatory is fortifying a land you control, you may tap fortified land and put the revealed card onto the battlefield tapped instead. If you do, unattach Celestial Observatory from fortified land.
