Mordenkainen's Orrery

If you would search your library for one or
more cards, exile twice that many cards from
the bottom of your library instead. You may play lands and cast noncreature spells from among cards exiled this way. You may spend mana as though it were mana of any color to cast those spells.
{1}{w/u}, {t}, Put a card from your hand on the bottom of your library: Target opponent gains control of Mordenkainen's Orrery until end of turn.
