Boba Fett, Bounty Hunter

When Boba Fett, Bounty Hunter enters the
battlefield, you may search your library for a
basic Forest card, reveal it, put it into your
hand, then shuffle your library.
Whenever a land enters the battlefield under
your control, if you control seven or more
lands, exile Boba Fett, then return him to the
battlefield transformed under his owner's
control.
