In Pokémon Emerald, Smeargle's only level-up move is Sketch which it will naturally have once captured but it will then learn the move at Level 11 and every 10 levels after however it will stop learning Sketch at Level 91. Sketch is an attack that will copy the move of a Pokémon's but only the last move that was used by the opposing Pokémon.

Sorry, you can't get Smeargle in Pokemon Leafgreen. All you can do is trade from one of the Hoenn games, like Sapphire, Ruby, or Emerald. :(
If you mean Artisan Cave, you can only find Smeargle.
Probably Smeargle.
