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.

Harbor Serpent's abilities care about lands with the land type Island, not necessarily lands named Island.

Price History
To study a single card is to glimpse the heart of a spell - a frozen moment of ambition, artistry, and arcane intent. Within each glyph lies a spark: a story untold, a duel turned, a destiny altered. Treat it not as mere parchment, dear seeker, but as a shard of the Multiverse itself.
