Doll House

You can target 1 Normal Monster in your GY with 0 ATK or DEF, or, if you control "Princess Cologne", you can target 2 such monsters instead; Special Summon 1 monster from your Deck with the same name as each target, as a Level 6 DARK monster. You can only use this effect of "Doll House" once per turn. When an opponent's monster declares an attack: You can attach 1 "Grandpa Demetto" you control to "Princess Cologne" you control as material, then end the Battle Phase.
