I don't think I have Dream Ball Scyther, but I can check again. Even so, Steel Wing must come from Gen. IV. Since I'm cloning TMs and Steel Wing is one I recognize as depreciated after that generation, it's one to be cloned if not already.
At the very least, a Steel Wing Scyther can be done. In HG/SS, it's only found in the Bug-Catching Contest, so I hope you don't mind if I clone that since finding it is FURIOUSLY random and you don't battle it like normal (meaning I was lucky to even get it), plus you only get that 20 minute window three times a week to locate it. Thus, I think it even comes in a special contest ball of some sort (meaning it might be impossible to use Apricorn Balls), but I may be mistaken. I apologize that I do not know offhand if mine is male or female.
I will check this evening. I may be busy for a bit here IRL. :)
