Dark Ariados MODN4 17

If your opponent has any Benched Pokémon, choose 1 of them and switch it with the Defending Pokémon, then flip a coin. If heads, the new Defending Pokémon is now Paralyzed.

The Defending Pokémon is now Poisoned. Flip a coin. If heads, the Defending Pokémon can't retreat until the end of your opponent's next turn and if the effect of an attack, Poké-Power, or Trainer card would change that player's Active Pokémon, that part of the effect does nothing.
