>>15680259If you want to be champ, then you have to be at least somewhat competent at playing in OU.
Do a lot of random battles on Showdown. It sets you up with a random player with a premade team that should be somewhat decent. Get experienced with the concept of competitive battling through that.
After a while, you should move on to the OU environment in Showdown. I'd recommend using a copypasta team to start off so you can learn the ropes. Everything you really need to know about OU are the common sets of the common pokemon. To be a good competitive player, you have to know what to expect from which pokemon, so you can act accordingly.
Here's an example of when you shouldn't champ. My second time or so champing, I was using shrekle against Heatran, which I did not know commonly carried Roar. After I set up a few Acupressures and he sets up his stuff, he just roars me out. I'm made to look like and idiot, and I also practically lose the battle because of it. That is exactly what you do not want to have happen when you're champing, and you can prevent this by being experienced enough with the game.
You need to be able to use uncommon, and not that good pokemon in an environment where over half of every pokemon used will be very common and very good, and you'll need to be able to put up a fight with them. You don't have to win your battles, and it's not expected for a champ to win every one, since you're using a randomly thrown together team and you're going up against OU: The Team: The Experience.
You need to be familiar with the OU metagame and the common strategies, so you can know what the fuck you're doing when you decide to champ. After you feel confident in your experience playing in OU, then you should try to champ.
Another thing, be sure you know the fucking rules of champing. First six 'mons suggested are the ones you use. Fuck, the first time I champed I randomly selected them, and I still feel uber fucking retarded to this day.
