When Graygulch Lurker dies, target opponent loses 2 life.

When Graygulch Turncoat enters, you may post a bounty on target creature. If you do, each opponent loses life equal to the number of bounty counters on creatures.

{T}: Add {C}.

{7}{G}: Monstrosity 6. (If this creature isn't monstrous, put six +1/+1 counters on it and it becomes monstrous.)

Reveal the top three cards of your library. You may put a land card from among them onto the battlefield tapped, then you may put a creature card from among them into your hand. Put the rest on the bottom of your library in any order.

When Grievous Buccaneer enters, it voyages. (If it isn't blocking or targeted by another spell or ability, it phases out.)
