When this card is sent from the field to the Graveyard, except when destroyed by battle, Special Summon 1 "Oyster Token" (Fish-Type/WATER/Level 1/ATK 0/DEF 0).
You can easily special summon this card with the help of Hammer Shark, once summoned you can activate card like Fish Depth Charge to send Oyster Meister to the graveyard and destroy a card on the field, while doing so Oyster Meister's effect will also be activated and a token will be summoned on your side of the field.
