3 Level 5 monsters
When this card in its owner's possession is destroyed by an opponent's card (either by battle or by card effect): You can target 1 Xyz Monster in your Graveyard; return that target to the Extra Deck. If this card has a "Utopia" monster as an Xyz Material, it gains this effect.
Once per turn: You can detach 1 Xyz Material from this card, then target 1 monster your opponent controls; destroy that monster, and if you do, inflict damage to your opponent equal to the destroyed monster's ATK on the field.
