how to become GOOD competetive player, well it has two parts- making a team and actual batting. when making a team the most importatn part is how to start the battle- will you trap the enemy with SR and spider web? will you boost with d-dance/ q-dance/ s-dance and start sweeping, or will you try to play it safe with various screens or taunt? how you open a battle will greatly affect your momentum.
the team should include a mega, a phys wall and a spec wall. you can have your starter a mega, but walls are there to take care of threats and should come with stuff like haze, roar, rapid spin or anything else that counter startegies you hate to deal with.
regarding actual battling, remember you are fighting a person and not a computer program. don't think just because a trick worked once it will work again.
