Get a Female Oshawott Dewott or Samurott.
You can get on by mating Oshawott Dewott or Samurott with a Ditto and keep hatching eggs until you get a female one. (but you only have 12.5% chance of getting it.)
Then breed it with any of the above Male Pokemon. It has to know Night Slash.
Then hatch an Egg for the results.
The Oshawott should know Night Slash
Absol learns the move Night Slash at level 41. Absol also learns the Psychic type version of Night Slash called Psycho Cut at level 47.
I think night slash because more Pokemon can learn slash but few can learn night slash if it weren't a TM
there is no night slash in diamond
Sceptile, to my knowledge, is incapable of learning Night Slash.
First, do not evolve your sneasel, second, find a heart scale, third go to the move relearner's house. Give him the heart scale and select your sneasel to relearn night slash

Oshawott's most powerful move (without cheats) is Hydro Pump-- Oshawott learns it at level 43. Hydro Pump is 120 power plus 60 power because Oshawott is a Water type- so that's 180 power.

Wing attack X Scissor Steel Wing Night Slash
Heracross will either have it when you catch it or you can travel to Pastoria City and go to the east side of town(the house next to the water) to the move relearner. You will need a heart scale. Talk to the guy in the house and he will allow you to get heracross night slash.
Pokemon that learn Night Slash through breeding (Egg Moves) in X and Y are: Sandshrew Farfetch'd Scyther Gligar Teddiursa Torchic Slakoth Nincada Zangoose Seviper Shinx Skorupi
