Emerald: My Team for the third gym

[Emerald_Fire]

Hi, people! :)
I'm having trouble beating the third gym leader in Pokemon Emerald.
Here's my team:

Combusken Level 26
Double Kick
Peck
Focus Energy
Ember
No Item

Aron Level 20
Metal Claw
Iron Defense
Mud-slap
Headbutt
Soft Sand

Lombre Level 24
Astonish
Fake Out
Absorb
Nature Power
No Item

Ralts Level 20
Growl
Confusion
Double Team
Teleport
No Item

Gulpin Level 20
Pound
Amnesia
Poison Gas
Sludge
No Item

Geodude Level 7 (Training it, due to Rock/Ground typing)
Tackle
Defense Curl
Mud Sport
--
No Item

I need suggestions. Is using a Geodude to avoid Electric damage wise? Should I evolve my Ralts? Should I add some other Pokemon? Help me please.

Leveling up your Geodude is easily your best bet. Get it to at least Lv. 16 (when it learns Magnitude) and you'll most likely be set. The only thing you'd have to worry about is confusion for Supersonics and Magneton's Sonicboom, but that'd be easy to heal off since you know it's always going to do 20. Plus you have Combusken to come in on Magneton and get some nice super-effective damage off if Geodude gets into troube. Hope this helps :)

Thanks. I managed to get to Flannery (going to fight her next), and my Graveler is now tied for second-strongest with my Combusken.

Now my only question is:
Should I evolve me Ralts? It's level 24, fyi.

 

[Pikayosh]

yes you should evolve ralts if you plan on using it for the E4.

I want it to learn a few moves earlier, so it's staying a Ralts.
Also, it's Male, so...
Yeah.
