Well, I assume you still haven't completed the Elite Four. But if you did, you could: Go to Giant Chasm, capture a Ditto, take it to the trailer by the Transfer Lab, trade for Rotom, go to the Mall that has the room with the boxes, transform Rotom into Grass type with the lawnmower...
Then you might be able to teach it cut... Don't know. Just checked Bulbapedia...
