“Once per turn: You can target 1 monster you control that attacked this turn; change that target to Defense Position. If this face-up card is destroyed while it is in a Monster Card Zone, you can place it face-up in your Spell & Trap Card Zone as a Continuous Spell Card, instead of sending it to the Graveyard.”
