Talk:Xyz Double Back

Impossible Effect?
Shouldn't the effect say something like "If you control no other monsters"? I can't read Japanese, so I can't translate the text on the card image myself, but the current listed effect ("If you control no monsters, when an Xyz monster you control is destroyed") seems kind of impossible. How can you control an Xyz monster if you control no monsters. Unless it's talking about you controlling no monsters after your Xyz monster is destroyed, in which case, having the effect say "No other monsters" would be much clearer.
