Please help me, I have absolutely NO idea XD

This sort of isn't the place to ask questions like this.

To answer your question, my personal pick would be Vibrava.

Mod close? :3

I'd go with the Exploud, frankly none of the choices you listed were ones I'd use with that team... Vibrava's nice, but you're probably gonna be down in two or three hits from Drake's all-dragon attack force.

Hariyama is actually pretty good, but you already have Blaziken. Registeel, I really don't know, but I don't like his normal moveset.

If you don't mind me saying, you should get rid of Explosion and Fake Out. Explosion is strong, yes, but in the Elite 4 you really don't want to inflict self-harm. It really doesn't help. Fake Out is just too weak of a move to be much help, and the opponent will hit you hard on the second turn anyway.

Kadabra's Focus Punch is another thing, it doesn't hit often and Kadabra is a special attacker, not a physical.

...Have I said too much? O-O;

Also, is this for R/S or Emerald?

I really gotta say Vibrava. Because Flygon owns. It is just AWESOME. If you can, replace steel wing with Earthquake though.

I'll go with Flygon. Its better than the other two, Hariyama eventually gets worse in my opinion and I never saw Exploud to be that useful. As for the Regis, I dislike the legendary use in the main game... If you dont care, then choose Regice, that will help most
