Grandpa Demetto (BROL-EN032)

You can detach 1 material from "Princess Cologne" you control; Special Summon up to 2 Normal Monsters with 0 ATK or DEF from your GY, each as a Level 8 DARK monster in Defense Position. If an Xyz Monster you control activates its effect by detaching a Normal Monster: You can target that Xyz Monster and 1 monster your opponent controls; destroy your opponent's monster, and if you do, inflict damage to your opponent equal to that Xyz Monster's Rank x 300. You can only use each effect of "Grandpa Demetto" once per turn.
