Captain Deathblade

When Captain Deathblade enters the battlefield,
you may search your library for a card named
Cursed Treasure of Deathblade, reveal it, put it
into your hand, then shuffle.
Whenever a zombie enters the battlefield from a graveyard, you may pay {u}. If you do, all pirates
you control gain islandwalk and swampwalk until
end of turn. Create two treasure tokens.
