To become the best player and duke it out with pro's

Hi, my name is Anthony Castillo and I'm 19yrs old. I play halo everyday and have played in a few competitions. I have been playing halo for 12 years and have been playing competitively for 3. I am currently 1700 csr in open que and 1580 in Controller. I am a player that will do whatever it takes to win no matter the cost of my k/d. I like to do a little bit of everything when it comes to objective game modes and slayer. I am looking for a team that will help me be the best I can be while also bringing out the best in them. I do want to get more experience in the competitive scene and am willing to go to LAN's or compete online.
