Gold 5 Support Main LF Serious Team

Hello, I am a Gold 5 support main. I have been playing league for 2 years this coming February. I did my placements in S5 to test out rank because it was the very end of the season and i got silver 4. In S6 I did placements and got B5 then worked my way up to Gold 5 playing support the whole season except for the hand full of games I was placed in top lane. I am a aggressive support, but can be flexible in lane. I know where I am going to be placing wards. I want a team that will be competing in tournaments and go as far as we want. My main support is Alistar lv 7 with over 340K mastery points Other supports I play are Braum, Trundle, Thresh, Tahm Kench, Annie, Nautilius, Bard, Morgana, Soraka, Poppy, Shen
