LF Competitive team for newbie to tournaments

I have made it to POA Gold this season and am looking for a competitive team to join tournaments with. In 3v3 I mostly feel comfortable going captain Grace is my most consistent winner or jungle. I acknowledge my stats in API sites are not the BEST for jungle Then again I have not had many games in jungle and my recent jungle record is pretty alright and I believe I can prove myself, but I also want a competitive team to be an opportunity to greatly improve my overall mechanical and team play skill. Also, I CAN lane, but the only AA carry I am comfortable with is Ringo and I normally do well with mages, so my lane pool is not the most flexible unlike my captain and jungle pool. I really want to try to get into tournaments and hopefully get my name out there somehow.
