Sea Serpent (30A-76) is a common creature — Serpent from the 30th Anniversary Edition set. It costs {5}{U} and has restrictive conditions: it can't attack unless the defending player controls an Island and must be sacrificed if you control no Islands. Its defensive and board-state contingent nature makes it primarily a tempo or situational card that rewards Island-heavy board states rather than consistent standalone offense.
