Bring out as many Xyz Monsters as possible, then Chain this to the Summoning. In the same turn, play something like "Black Rose Dragon" or "Dark Hole" so that cards can be destroyed on your opponents side of the field while your Xyz Monsters remain unharmed.
Take control of an opponent's Xyz Monster, then activate this card. This way, your Xyz Monsters will not have to lose any Xyz Material.
This card can be used to negate the destruction of "Number 39: Utopia" by its own effect, so that there is no worry about it being selected as an attack target by a weak monster and being destroyed in the process.
