Second Gym Leader Help in Pokemon Platinum

My starter pokemon is Prinlup at level 24 and my second strongest one is Luxio at 23. The only flying move that prinlup knows is peck, and it doesn't seem to be doing much damage against the leader's grass type pokemon. Luxio isn't doing much damage either. If only I had a fire type or some type that is effective against that gym leader.

The problem is that the only pokemon I've encountered up to this point are either grass or rock which doesn't help in any way.

What can I do?

Peck is a flying move, and I used it on the leader's pokemon, but it doesn't do much damage. It doesn't seem like flying pokemon help.

There was a crapload of ponyta on my way there..DirtyDozen520

Catch a ponyta or starly and you'll be laughing. Even any old bug type should do the trick (as along as it has evolved once or twice).

to the right of that city are wild ponytas and there are many =) try that one :)

staravia also with wing attack or a psychic pokemon, like abra that u trade for a machop or the rare wild abra..... level 16 and u got confusion and a really fast pokemon with very high special attack =) rememebr that most are also poison =)

I found a ponyta on my way there Im sure if u spend some time in the highgrass near the city or on the ones just outside it ( i mean outiside where you go to the next city after getting the medal and stuff).. I leveled up that baby and breezed thorugh my second medal with one hit kills on everyoneincluding the gym leaders last poke, my ponyta was 21 or22 when i faced them but Im guessing even a 15, 16 or even lower would have a really easy time beating all of them but the GL last one...
