Sketch is a move that copies the last move used by the other pokemon. This allows Smeargle to learn any move (Not named Struggle) in the game. However, it doesn't work in PVP. This means you must use other methods to get moves on Smeargle. Methods: First method is to get a pokemon with the move you want to sketch and more speed than your smeargle, then enter a double battle with an NPC trainer. Make pokemon A use the move, then make Smeargle sketch said move by targeting the pokemon.
