Poké-POWER ⇢ Ectoplasm
If Dusknoir is your Active Pokémon 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. As long as you have Dusknoir LV.X as a Stadium card in play, put 1 damage counter on each of your opponent’s Pokémon between turns. If another Stadium card comes into play or Dusknoir LV.X is discarded by the effects of any attacks, Poké-Powers, Poké-Bodies, Trainer, or Supporter cards, return Dusknoir LV.X to your hand.
