Which Electric type for my Pearl Team?

well u could go with Ampharos since it has good attack but can I suggest another pokemon, I would go with Lanturn especially if it has the special ability of VOLT ABSORB (make sure it does have this ability) volt absorb is good cause electric attacks wont hurt him like swamper. Also u if u want just keep electivire but raise his attack speed and defense by giving him Calcium,Iron,Zinc and Hp up.
