Second, go on pokémon showdown and watch some other people battle. It's worth a thousand words.
Third, make your own team (again, on showdown) and get your ass kicked in a couple times. Fourth, make a better team and get your ass kicked in a little less.
Fifth, travel with Showderp a little. It gets old pretty fast, but watching the champs play with shitmons and win is surprisingly helpful.
Sixth, realize that doubles are the superior format, and stop playing singles.
Seventh, once you've gotten gud enough, breed a team in-game. Eighth, go to the battle spot and rek shit.
Ninth, realize that you've wasted a month or so of your life, and play a different game.
