Diamond 5 looking for ranked team for last push

I can fill. I do main Jungle/Top/Mid.

I am a Nidalee 1 trick, I have 75 matches played with her and a record of 58 wins - 17 losses (77%). Can play other champions like Fiora, Riven, Elise, Caitlyn, Ashe, Orianna, Ahri, those are like main champions.

Prefer to be on a Plat+ only team, or a ranked 5s team that's already placed high.
