If Dusknoir Lv.X is knocked out by darkness lost, does it become a stadium or does it go into the lost zone?
The wording on Giratina Lv.X is:
If any of your opponent's pokemon would be Knocked Out by damage from this attack, put that pokemon and all cards attached to it in the Lost Zone instead of discarding it.
And Dusknoir:
If Dusknoir is your active pokemon and would be Knocked Out by damage from your opponent's attack, you may discard all cards attached to Dusknoir Lv.X and put Dusknoir Lv.X as a stadium card into play instead of discarding it. This counts as Dusknoir being Knocked Out and your opponent takes a prize card...If another Stadium card comes into play or if Dusknoir Lv.X is discarded by the effect of any attacks, Poke-Powers, Poke-Bodies, Trainer, or Supporter cards, return Dusknoir Lv.X to your hand.
