Team movesset help

[LgnKrn]

Ok, I've played ruby like 15 times now, but never got further the the last badge, because my Pokemon kept fainting, so I've trying to figure out better move sets for my team:
(Currently at slateport city training my weaks)

Lv. 12 Electrike
Nature: Bold
Moves: Tackle, Thunder Wave, Leer, Howl

Lv. 18 Aron
Nature: Bashful
Moves: Tackle, Metal Claw, Mud-slap, Headbutt

Lv. 20 Gyarados
Nature: Modest
Moves: Tackle, Splash, Bite

Lv. 19 Cumbusken
Nature: Bashful
Moves: Scratch, Double kick, Focus energy, Ember

Lv. 22 Swellow
Nature: Lax
Moves: Peck, Wing attack, Focus energy, Quick attack

Then a Spheal one I can get it

When I played before, I was ALL about offense :oops:

The #1 Rule for this forum:
Post ONLY level 100 teams for competitive battling.

Do NOT post in-game or Wi-Fi teams!

Oh noes!

However I can tell you that anything will beat the "Elite" Four and the Gym Leaders. Seriously I wouldn't sweat it. That team after growing 40 levels will crush the e4 (like all teams) so don't worry about it.

Obviously this isn't competitive so don't worry too much about the movesets. Also I wouldn't use any of your good TMs as you'll want them if you get into EV training or what have you.
