Relatively New Player Looking for either a support or adc for Duo low-high silver

Hey everyone, I just started playing league about a year ago, though I have only recently started getting into it. I feel like my mechanics are not too shabby for how long I have been playing and my understanding of things like types of champs, item builds, and masteries are not too bad as well. However whenever I play 5v5 normals I always feel like I need help understanding what things I should do after the laning phase and when I should do them. I feel as if I had someone who was near my skill level, but perhaps has been playing longer than I have then maybe I can learn that part of the game easier. I can play adc champs such as Twitch, Xayah, Lucian, Ashe, Sivir, Jhin, Miss Fortune, and Tristana proficiently and am trying to learn Kogmaw, Ezreal, and Kallista currently. In terms of support I can play Lux, Blitzcrank, Janna, Thresh, Miss Fortune, Rakan, Galio, and Gragas. I know not all of those are specifically known for support, but they can perhaps work there in the right match up. Also looking to learn more support champs as well. I also watch a decent amount of pro games which might also help out with my lack of concrete in game knowledge.

TLDR; I am just looking for someone who is willing to help me learn as a player and perhaps we can kick some butt in ranked. Don't want anyone who is just going to be toxic, so just save us both some time and don't bother replying. Thanks everyone, Praeceps/ IGN: MG Gank Magnet
