BW Metagame/OU competitive battling guide?

[HolyChipmunk]

I'm trying to teach my friend the basics, but he's just not getting it.
Is there a (newer) guide of some sort with explanations of things like hazards,sweepers,walls, and that sort of stuff? The only one I found was this, but that focuses more on game mechanics. It would be much appreciated.

Scroll down to "Reference Lists and Strategy" and read away. For 5th generation, head over to C&C and browse the articles and analyses there.

There is no singular article that will answer every single question, hence why there are VERY comprehensive (the most you'll find on the internet anyways) guides to individual aspects (hazards, wall breakers, stall, whatevs).
