Switch in your own smeargle and sketch yourself recycle. You can also face a ditto with the mon that have the move you want to copy. Besure it know only ONE move. Then switch in your smeargle and sketch.
Simple in theory, but it make for a lots of hoops to jump through. But in the end, very worth it.
