I just finished training a Scyther on Diamond.
Ev trained for Attack(349).
Moveset:
Wing Attack
X-Scissor
Night Slash
Swords Dance
Now when I evolve it into a Scizor should I replace one of the moves with Iron Head? If so which one?
If your Scyther's ability is technician I would go with Bullet Punch instead of Iron Head. I think I'd trash Wing Attack for the steel move. Also, Roost may be a good move to teach before evolving, so that if you're using a Life Orb as your Scisor's item you could recover. If you're using a different item, then you don't need Roost. Also, if you're using a choice item you may consider Bullet Punch over Iron head for it's speed, and it's gain in power thanks to the choice item. However, if you're using the Choice item that ups speed, go with Iron Head...
My team now has 4 pkmn at lv 98...
