The Dread Pirate Roberts

Pirates you control get +1/+0 for each Treasure
you control.
Whenever you tap a Pirate you control, create
a Treasure token. (It's an artifact with "{t},
Sacrifice this artifact: Add one mana of any color.")
Sacrifice five Treasures: Search your library for
an artifact and a land card, put them onto the
battlefield, then shuffle.
