Brook, Immortal Bard

What keeps me alive-If you control a legendary
pirate, you may cast Brook, Immortal Bard from
your graveyard or from exile.
Yohoho!-Other legendary pirate creatures you
control have "Whenever this creature becomes
the target of a spell or ability you don't control,
you may change the target of that spell or ability
to Brook, Immortal Bard."
