So you could learn to draw
Smeargle is the Pokemon that can learn sketch, and its its only move
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.
It is important to have a general idea of the size of the sketch. If you don't your sketch will not be proportionate. It also helps if you have a general idea of what you are sketching.
Heatran, but smeargle can if it uses sketch after heatran does.
Darkrai is the only one who can learn it by level, although Smeargle can use Sketch to learn it as well.
knowing how to sketch
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.
i think it copys metomine i am not sure
Well, technically Smeargle can't learn anything else by leveling up except Sketch (every 10 levels). But what Sketch does is permanently copy a foe's move. This allows for an infinite move pool in some cases. Example: Smeargle is fighting an Alakazam. Alakazam uses Phychic! Smeargle uses Sketch! If it works, Smeargle can now use Phychic permanently! It's really cool.
