Soudetoile Insecte Numérique SHVI-FR035

Not usable as Xyz Material for an Xyz Summon, except for the Xyz Summon of an Insect-Type monster. Once per turn, you can target 1 face-up Attack Position monster you control, change it to Defense Position, and if you do, Special Summon 1 Level 3 Insect-Type monster from your hand in Defense Position. An Xyz Monster that was Summoned using this card on the field as Xyz Material gains this effect. If it is Xyz Summoned, the DEF of all face-up monsters your opponent controls becomes 0, and also, change them to Defense Position.
