Once during your turn (before your attack), when you put Gliscor LV.X from your hand onto your Active Gliscor, you may choose 1 of the Defending Pokémon. That Pokémon is now Paralyzed and Poisoned.
Night SlashYou may switch Gliscor with 1 of your Benched Pokémon.
Put this card onto your Active Gliscor. Gliscor LV.X can use any attack, Poké-Power, or Poké-Body from its previous level.
Ninjask's "Night Slash" attack has an effect where it may switch with a Benched Pokemon. If it switches, would the Defending Pokemon's Rock Guard effect take place on Ninjask or on the new Pokemon?
Rock Guard references putting counters on "the Attacking Pokemon", so Ninjask would still take the damage counters even if it goes to the Bench.
