My name would be Alice, and I'd master in the Steel Type~ (cus steel is awesome)
Aggron
Scizor
Metagross
Empoleon
Scarmory
Bisharp
As long as you don't pick a Fire Type for your starter, you can't beat me cB
And even then, it sucks for you since I added Empoleon. :I
Fighting types would suck too, since Skarmory has high speed, but whatever lol...I just love Steel Types, even when other people don't.
