Sketch (スケッチ Sketch) is a Normal-type move introduced in Generation II. It is Smeargle's signature move. Smeargle can learn the move every ten levels or by going to a Move Tutor. Sketch cannot copy Chatter or Struggle.
It enables the user to learn a move used by the foe. Once used, the move Sketch disappears. It learns sketched attacks permanently. This also means the Pokémon can learn legendary's signature moves like Judgment or Shadow Force. In battles Harison had used it many times
