Your Opinions?

[GamerFreak]

Well, I have been breeding for Pichus with a hasty or naive nature, and the best IVs possible. So far, I haven't had the best success. My thought for the future are this, and I need you to help me improve it, and what else I should add to my new team.

Raichu @ ????
Physical Sweeper
Hasty or Naive Nature
(Suggested EVs?)
(Suggested IVs?)
Volt Tackle
Giga Impact (Not sure)

So, I just need your opinions here, and what I should add.
