Numéro 102 : Sentinelle Séraphin Étoile JOTL-FR053

3 Level 4 LIGHT monsters Once per turn, you can detach 1 Xyz Material from this card, then target 1 face-up monster your opponent controls, halve its ATK, and also negate its effects. If this face-up card on the field would be destroyed, you can detach all Xyz Materials from it instead. If you do, all battle damage you take this turn is halved.
