[It's going to be a tough battle, as far as Duplica knows Scizor doesn't learn any moves that will be effective in this situation. And with that speed she has little time to tell her Ditto to do anything save for 'dodge it'. Though Ditto tries to back off the Slash attack soon lands and sends Ditto sliding backwards.]
It's fast Ditto, try and match it with a Metal Claw!
[If it knows Slash then it must know Metal Claw. Ditto flies in with its pincers ready to retaliate!]
