support main looking for ranked 5s team

As my name suggests, I am indeed a bard main. However my champion pool is deep and has some unconventional picks in it as well. I play for the team and not myself. I was gold last season in ranked fives and am looking to go the distance again this season. My support champion tier list is as follows

Tier 1: bard, shen, nautilus, soraka and morganna.

Tier 2: braum, than kench, blitzcrank, thresh, nami, karma, sona, and lulu.

Tier 3: shaco, swain, brand, velkoz, lux, malphite, rammus, leona, janna, and LeBlanc
