Sea Serpent - Fourth Edition (Common)

Sea Serpent is a 5/5 creature from the Fourth Edition set that can only attack if the defending player controls an Island. This limitation makes it a strategic choice in blue control decks, as it can deter opponents from attacking if they lack Islands. However, if you don't control any Islands, you'll have to sacrifice it, so careful management of your mana base is essential.
