Every 10 levels.
anything (sketch) send him in a duble battl and he can learn stuff like judment (you half to have his partner use the move you want it to now) use sketch on its partner and there
yes, but smeargle needs to know another move (besides sketch)and use sketch when the flyer lands.

Only smeargle can learn sketch.It copies the foes last move.If arceus uses judgment then smeagle can learn it!
It all depends on if you mean the TM or using sketch. If you are using sketch then I think you keep it but, if you try to teach it using the TM most likely you won't get it.
