Seadra from the Pokémon Japanese SM3H: To Have Seen the Battle Rainbow set is a Common card, numbered 017/051, that appears in competitive-era Sun & Moon releases. Collectors track it as an accessible base-set entry rather than a high-value rarity, with current market listings at $0.00. Condition and grading remain the primary factors that could alter interest, since ungraded copies are abundant. Its presence helps complete Japanese set collections and checklists.
