Answer 1

Sorry but the only way to get Scizor is to trade Scyther with a metal coat.
If you need more information on any of the two Pokemon there here you go!

Scizor
Scyther

Hope this helps :)

If you have black and you want a scizor trade me the Scyther with the metal coat and i will trade it back to you. Or you could trade the scyther and then i give it a metal coat then i trade it back to you.
I love scizor and my level 100 one :)
