Rulings:

• 8/15/2010 Harbor Serpent’s abilities care about lands with the land type Island, not necessarily lands named Island.
• 8/15/2010 The second ability checks how many Islands are on the battlefield (regardless of who controls them) only as attackers are declared. Once Harbor Serpent is declared as an attacker, it will continue to attack even if the number of Islands on the battlefield falls below five.
