I need a team 5 vs 5 Ranked

So every ranked game sucks because it takes one person who is terrible at league to ruin the whole ranked gaming experience. I keep getting demoted because of this. I was in silver V and now i'm in bronze II I need help on making a team so I can at least win some games. I want to rank up but it depends on there team mates and that they know what they are doing with their champions, lanes, and roles on the map. I'm wishing our team could rank up together.

I can top lane, jungle, support, and mid, but i'm terrible at adc.

These are the camps I main:

thx and please consider.
