mlg questions/ looking to play cod with some GOOD players on CoD ps3

so i have recently made my mlg account and i mostly play call of duty series but i am a bit tired of playing with a awful team... so i was hoping to play call of duty with some decent players on domination, hardpoints .ect
if you want to add me on psn and have some games together add Nustervox

here is what i posted on mlg so it may be repetavive with what i just said but i have question about mlg and dont whant to re write it all

so i have recently made my mlg account and i mostly play call of duty series but i am a bit tired of playing with a awful team... so i would like to play with a good team or players i looked around mlg and found about teams but was still a little confused if i join a team do i have to enter tournaments .ect all the time or do we just play on game modes and win matches or both?, also if you are in a team is it optional whether you enter a tournament

also on mlg you can watch lives games... are they tournaments
or just a game between 2 teams.

if on a team you played on game modes with people from your team (ime guessing there is more than 6 people on a team)
then i would like to join one

if not i would like to just play with some good players on domination, hardpoints .ect

and this applies to teams i am 13 so i have a high voice but its not annoyingly hight i also have a mic so i can be of use and talk to who i am playing with
also i am not a bad player myself
