● While this card is equipped to a monster, if the equipped monster battles a monster, that monster's effects are negated. ● While this card is equipped to a monster by its own effect, if the equipped monster would be destroyed or if you would take damage from a card effect, you can send this card to the Graveyard instead. During your Main Phase, if this card was sent to the Graveyard by this effect: You can send 1 card from your hand to the Graveyard; Special Summon this card from your Graveyard.
