Aristera & Dexia Gogogo MP18-FR097

As long as another "Gogogo" monster is on the Field, your opponent's monsters cannot target "Gogogo" monsters with an attack, and also, your opponent cannot target "Gogogo" monsters on the Field with card effects. An Xyz Monster that has been Summoned using only this card and other "Gogogo" monsters as Material gains this effect. When it is Xyz Summoned, you can target 1 monster in face-up Attack Position your opponent controls, change it to Defense Position, and if you do, change its DEF to 0.
