The best starter to use is Cindiquil. Here's the moves that would make it almost unbeatable:
1. Flamewheel (Quilivia learns it I think 25)
2. Earthquake (TM found @ Victory Road)
3. Thunderpunch (Typholsion can only learn the TM; buy TM at the store in Goldenrod)
4. Any other move (i reccommend a fighting move)
Flamewheel hurts grass and steel pokemon. Earthquake hurts fire, electric, and possibly flying. Thunderpunch hurts water and flying. And the fighting move hurts normal Pokemon.
Hope this has helped
