|Set:||Ghosts From the Past: The 2nd Haunting|
|Card type:||Effect Monster|
When this card is Normal Summoned: You can change this card to Defense Position, and if you do, inflict 500 damage to your opponent. If this card is destroyed by battle or sent to your GY by a card effect: You can add 1 Level 8 Rock monster from your Deck to your hand, or if "Fossil Fusion" is in your GY, you can Special Summon it instead. For the rest of this turn, you cannot activate cards, or the effects of cards, with the same name as that card. You can only use this effect of "Shell Knight" once per turn.
