Oyster Meister is able to Special Summon Oyster Token which is considered Fish-type monster, when being destroyed by card effect. Therefore, it grants Golden Flying Fish another “ammunition” to destroy another card on the Field. Using Powerful Rebirth on Oyster Meister will further grant you more “ammunition” for Golden Flying Fish to potentially destroy all the cards on your Opponent’s side of the Field.
Hammer Shark is able to Special Summon Oyster Meister to the Field from your Hand, while Hammer Shark itself can be Tributed by Golden Flying Fish to destroy your opponent’s cards. Beautunaful Princess can also be used to Special Summon Golden Flying Fish from your Deck to your Field.
