Smack Down removes the effects of Magnet Rise and Telekinesis. Smack Down makes its target vulnerable to Ground-type moves and Arena Trap even if it is Flying-type or has Levitate. This effect lasts until the affected Pokémon switches out. This effect does not occur if the target is behind a substitute. It can hit Pokémon during the semi-invulnerable turns of Fly, Bounce, and Sky Drop. If it hits a Pokémon using Fly or Bounce, it will knock it down, cancelling the move; if it hits a Pokémon using or affected by Sky Drop, it will not be knocked down. A Pokémon hit with Smack Down can still use these moves on subsequent turns.
