Doll House

You can target 1 Normal Monster with 0 ATK or DEF in your GY; Special Summon 1 monster with the same name from your Deck as a Level 6 DARK monster. If you control "Princess Cologne", you can target 2 monsters, instead. 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 your "Princess Cologne" as material, then end the Battle Phase.
