2 Level 4 monsters Dragon-Type monsters you control cannot be destroyed by battle, except "Queen Dragun Djinn". Once per turn: You can detach 1 Xyz Material from this card to target 1 Level 5 or higher Dragon-Type monster in your Graveyard; Special Summon that target. It cannot attack this turn, and its effects are negated.
It is a "Djinn" Xyz monster which means it is part of the arcthetype. Some goes for Number 65 and CXyz Mechquipped Djinn Angeneral. They're not really intended to be used with the standard Djinn orchestra archetype but they still get the support.
