Bucky, the Winter Soldier

When Bucky enters the battlefield, you may search
your library for an artifact card, reveal it, and put
it into your hand. If you do, shuffle your library.
{3}{w}{u}: Exile Bucky. Return it to the battlefield
under its owner's control at the beginning of the
next end step.
