[SCD New] Gogogo Aristera & Dexia

While you control another “Gogogo” monster, your opponent cannot target “Gogogo” monsters you control for attacks or card effects.
An Xyz Monster that was Summoned using only this card and other “Gogogo” monsters as Xyz Material gains this effect.
• When this card is Xyz Summoned: You can target 1 face-up Attack Position monster your opponent controls; change it to Defense Position, and if you do its DEF becomes 0.
