support main 15+ champion pool L4 serious ranked 5 man team

Arctic Snow Wolf Last season silver 4 couldnt climb because end of season Currently B3, having hard time with bronze players feeding top or mid. I havent lost bottom lane at all since this season started, I have only tied 2 times out of 41 games. half ive lost thanks to top and mid lane being fed or jungle gets fed. Champion pool: Alistar, TK, Thresh lv 5 mastery. Nautilus lv 4 mastery. Braum, blitz, malphite lv 3 mastery. Brand, Annie, poppy, Orianna, Sona lv 2 mastery. Shen, Nunu, Zyra, voli, janna lv 1 mastery. Karma, soraka, Morgana, Taric in the back, and im working on buying Nami, Leona and the rest of supports. I am a aggressive support, looks to feed my adc early game, i work on keeping the enemy adc at low farm by abusing them as much as i can. I look to tower dive when we can especially when I play alistar and he has his ult.
