Look for 5s team or sub for one

Started late season 5 Im B1 (everyone stops reading here). I am on a silver team with two plats so I can play with higher elo and hold my own. The main point is I play for the team and know the champs I play well (270K on ekko). Im just looking for a chance to show im worth having as a sub or be on a team even though im B1. Id prefer 5s bc of communication and the teamwork of 5s. Thats why I dont put alot of time into climbing the ladder. Id rather play with a team all communicating and want to win not get fed and throw the game for a KDA.
