Preparative Spell

As Preparative Spell enters the battlefield, if you
cast it, choose a nonland card name.
Whenever an opponent casts a spell with the
chosen name, or whenever a permanent with the
chosen name enters the battlefield under an
opponent's control, you may exile Preparative
Spell. If you do, search your library for a card,
reveal it, put it into your hand, then shuffle.
