support LF serious 5v5 team

Hello, I am looking for a serious 5v5 team that wants to compete in tournaments and go places. I am a support main Alistar, thresh, TK, Nautilus, Braum, Blitz, Leona. Working on the squishy supports Non meta supports Malphite, Shen, Rammus, Poppy Was on a previous team that said my alistar was really strong but parted away because a couple people did not like me, so i was kicked without anyone talking to me about it. Might be able to get someone from that team you can talk to as a reference. was Silver last season. I am Bronze right now due to trying to climb as a support main, Its not working lol and very frustrating so i might start playing top until i get out. Please do no judge me on the Bronze rank let me show you want I can do as a support before you judge me. Thank you for reading this have a great day hope to hear from you or one of your teammates about a tryout
