Well, from looking at your other thread, I would say that your Snorlax/Gyarados/Snorlax is a relatively good team, so I don't see why you wouldn't use that.
But anyway, you aren't really giving us a broad subject to use here. Personally, maybe if you looked around a got a general idea of what you wanted to use, it would be better. Even listing types you would like to include would help, as then someone could list some good pokemon to use from there.
I really don't mean to sound rude, and if I do, I really apologize. If you could list some certain things you would like to include, it would help, as there are a ton of useful pokemon to use in the frontier. It's just that it's so vague, I'm not too sure what to tell you. I'm just asking if you could possibly make it less vague, it would be much easier to help you.
