X, Captain's Most Trustworthy

Whenever another Pirate you control enters, you
may pay {b} and 1 life. If you do, it explores. (Reveal
the top card of your library. Put that card into your
hand if it's a land. Otherwise, put a +1/+1 counter
on the creature, then put the card back or put it into
your graveyard.)

{2}{u}{b}: Return X, Captain's Most Trustworthy
from your graveyard to the battlefield. It's an enchantment. Shuffle your graveyard into your
library.
