Flying When Cavalier of Gales enters, draw three cards, then put two cards from your hand on top of your library in any order. When Cavalier of Gales dies, shuffle it into its owner's library, then scry 2.
Flying When Dungeon Geists enters, tap target creature an opponent controls. That creature doesn't untap during its controller's untap step for as long as you control Dungeon Geists.
Return all nonland permanents to their owners' hands. If you return four or more nontoken permanents you control this way, you may put a permanent card from your hand onto the battlefield.
